  • Scalable Bandwidth Shaping Scheme via Adaptively Managed Parallel Heaps in
           Manycore-Based Network Processors
    • Abstract: Taehyun Kim, Jongbum Lim, Jinku Kim, Woo-Cheol Cho, Eui-Young Chung, Hyuk-Jun Lee

      Scalability of network processor-based routers heavily depends on limitations imposed by memory accesses and associated power consumption. Bandwidth shaping of a flow is a key function, which requires a token bucket per output queue and abuses memory bandwidth. As the number of output queues increases, managing token buckets becomes prohibitively expensive and limits scalability. In this work, we propose a scalable software-based token bucket management scheme that can reduce memory accesses and power consumption significantly. To satisfy real-time and low-cost constraints, we propose novel parallel heap data structures running on a manycore-based network processor. By using cache locking, the performance of heap processing is enhanced significantly and is more predictable.

  • Automated Integration of Dual-Edge Clocking for Low-Power Operation in
           Nanometer Nodes
    • Abstract: Andrea Bonetti, Nicholas Preyss, Adam Teman, Andreas Burg

      Clocking power, including both clock distribution and registers, has long been one of the primary factors in the total power consumption of many digital systems. One straightforward approach to reduce this power consumption is to apply dual-edge-triggered (DET) clocking, as sequential elements operate at half the clock frequency while maintaining the same throughput as with conventional single-edge-triggered (SET) clocking. However, the DET approach is rarely taken in modern integrated circuits, primarily due to the perceived complexity of integrating such a clocking scheme. In this article, we first identify the most promising conditions for achieving low-power operation with DET clocking and then introduce a fully automated design flow for applying DET to a conventional SET design.

  • Design Methodology of Fault-Tolerant Custom 3D Network-on-Chip
    • Abstract: Katherine Shu-Min Li, Sying-Jyan Wang

      A systematic design methodology is presented for custom Network-on-Chip (NoC) in three-dimensional integrated circuits (3D-ICs). In addition, fault tolerance is supported in the NoC if extra links are included in the NoC topology. In the proposed method, processors and the communication architecture are synthesized simultaneously in the 3D floorplanning process. 3D-IC technology enables ICs to be implemented in smaller size with higher performance; on the flip side, 3D-ICs suffer yield loss due to multiple dies in a 3D stack and lower manufacturing yield of through-silicon vias (TSVs). To alleviate this problem, a known-good-dies (KGD) test can be applied to ensure every die to be packaged into a 3D-IC is fault-free.

  • Approximate Energy-Efficient Encoding for Serial Interfaces
    • Abstract: Daniele Jahier Pagliari, Enrico Macii, Massimo Poncino

      Serial buses are ubiquitous interconnections in embedded computing systems that are used to interface processing elements with peripherals, such as sensors, actuators, and I/O controllers. Despite their limited wiring, as off-chip connections they can account for a significant amount of the total power consumption of a system-on-chip device. Encoding the information sent on these buses is the most intuitive and affordable way to reduce their power contribution; moreover, the encoding can be made even more effective by exploiting the fact that many embedded applications can tolerate intermediate approximations without a significant impact on the final quality of results, thus trading off accuracy for power consumption.

  • Parallel High-Level Synthesis Design Space Exploration for Behavioral IPs
           of Exact Latencies
    • Abstract: Benjamin Carrion Schafer

      This works presents a Design Space Exploration (DSE) method for Behavioral IPs (BIPs) given in ANSI-C or SystemC to find the smallest micro-architecture for a specific target latency. Previous work on High-Level Synthesis (HLS) DSE mainly focused on finding a tradeoff curve with Pareto-optimal designs. HLS is, however, a single process (component) synthesis method. Very often, the latency of the components requires a specific fixed latency when inserted within a larger system. This work presents a fast multi-threaded method to find the smallest micro-architecture for a given BIP and target latency by discriminating between all different exploration knobs and exploring these concurrently.

  • Obfuscation-Based Protection Framework against Printed Circuit Boards
           Unauthorized Operation and Reverse Engineering
    • Abstract: Zimu Guo, Jia Di, Mark M. Tehranipoor, Domenic Forte

      Printed circuit boards (PCBs) are a basic necessity for all modern electronic systems but are becoming increasingly vulnerable to cloning, overproduction, tampering, and unauthorized operation. Most efforts to prevent such attacks have only focused on the chip level, leaving a void for PCBs and higher levels of abstraction. In this article, we propose the first ever obfuscation-based framework for the protection of PCBs. Central to our approach is a permutation block that hides the inter-chip connections between chips on the PCB and is controlled by a key. If the correct key is applied, then the correct connections between chips are made.

  • A Single-Tier Virtual Queuing Memory Controller Architecture for
           Heterogeneous MPSoCs
    • Abstract: Yang Song, Kambiz Samadi, Bill Lin

      Heterogeneous MPSoCs typically integrate diverse cores, including application CPUs, GPUs, and HD coders. These cores commonly share an off-chip memory to save cost and energy, but their memory accesses often interfere with each other, leading to undesirable consequences like a slowdown of application performance or a failure to sustain real-time performance. The memory controller plays a central role in meeting the QoS needs of real-time cores while maximizing CPU performance. Previous QoS-aware memory controllers are based on a classic two-tier queuing architecture that buffers memory transactions at the first tier, followed by a second tier that buffers translated DRAM commands. In these designs, QoS-aware policies are used to schedule competing transactions at the first stage, but the translated DRAM commands are served in FIFO order at the second stage.

  • SSAGA: SMs Synthesized for Asymmetric GPGPU Applications
    • Abstract: Shamik Saha, Prabal Basu, Chidhambaranathan Rajamanikkam, Aatreyi Bal, Koushik Chakraborty, Sanghamitra Roy

      The emergence of GPGPU applications, bolstered by flexible GPU programming platforms, has created a tremendous challenge in maintaining high energy efficiency in modern GPUs. In this article, we demonstrate that customizing a Streaming Multiprocessor (SM) of a GPU at a lower frequency is significantly more energy efficient compared to employing DVFS on an SM designed for a high-frequency operation. Using a system-level CAD technique, we propose SSAGA—Streaming Multiprocessors Synthesized for Asymmetric GPGPU Applications—an energy-efficient GPU design paradigm. SSAGA creates architecturally identical SM cores, customized for different voltage-frequency domains.

  • TEI-power: Temperature Effect Inversion--Aware Dynamic Thermal Management
    • Abstract: Woojoo Lee, Kyuseung Han, Yanzhi Wang, Tiansong Cui, Shahin Nazarian, Massoud Pedram

      FinFETs have emerged as a promising replacement for planar CMOS devices in sub-20nm technology nodes. However, based on the temperature effect inversion (TEI) phenomenon observed in FinFET devices, the delay characteristics of FinFET circuits in sub-, near-, and superthreshold voltage regimes may be fundamentally different from those of CMOS circuits with nominal voltage operation. For example, FinFET circuits may run faster in higher temperatures. Therefore, the existing CMOS-based and TEI-unaware dynamic power and thermal management techniques would not be applicable.

  • Using CoreSight PTM to Integrate CRA Monitoring IPs in an ARM-Based SoC
    • Abstract: Yongje Lee, Jinyong Lee, Ingoo Heo, Dongil Hwang, Yunheung Paek

      The ARM CoreSight Program Trace Macrocell (PTM) has been widely deployed in recent ARM processors for real-time debugging and tracing of software. Using PTM, the external debugger can extract execution behaviors of applications running on an ARM processor. Recently, some researchers have been using this feature for other purposes, such as fault-tolerant computation and security monitoring. This motivated us to develop an external security monitor that can detect control hijacking attacks, of which the goal is to maliciously manipulate the control flow of victim applications at an attacker’s disposal. This article focuses on detecting a special type of attack called code reuse attacks (CRA), which use a recently introduced technique that allows attackers to perform arbitrary computation without injecting their code by reusing only existing code fragments.

  • Fundamental Challenges Toward Making the IoT a Reachable Reality: A
           Model-Centric Investigation
    • Abstract: Yuankun Xue, Ji Li, Shahin Nazarian, Paul Bogdan

      Constantly advancing integration capability is paving the way for the construction of the extremely large scale continuum of the Internet where entities or things from vastly varied domains are uniquely addressable and interacting seamlessly to form a giant networked system of systems known as the Internet-of-Things (IoT). In contrast to this visionary networked system paradigm, prior research efforts on the IoT are still very fragmented and confined to disjoint explorations of different applications, architecture, security, services, protocol, and economical domains, thus preventing design exploration and optimization from a unified and global perspective. In this context, this survey article first proposes a mathematical modeling framework that is rich in expressivity to capture IoT characteristics from a global perspective.

  • HoPE: Hot-Cacheline Prediction for Dynamic Early Decompression in
           Compressed LLCs
    • Abstract: Jaehyun Park, Seungcheol Baek, Hyung Gyu Lee, Chrysostomos Nicopoulos, Vinson Young, Junghee Lee, Jongman Kim

      Data compression plays a pivotal role in improving system performance and reducing energy consumption, because it increases the logical effective capacity of a compressed memory system without physically increasing the memory size. However, data compression techniques incur some cost, such as non-negligible compression and decompression overhead. This overhead becomes more severe if compression is used in the cache. In this article, we aim to minimize the read-hit decompression penalty in compressed Last-Level Caches (LLCs) by speculatively decompressing frequently used cachelines. To this end, we propose a Hot-cacheline Prediction and Early decompression (HoPE) mechanism that consists of three synergistic techniques: Hot-cacheline Prediction (HP), Early Decompression (ED), and Hit-history-based Insertion (HBI).

  • CDTA: A Comprehensive Solution for Counterfeit Detection, Traceability,
           and Authentication in the IoT Supply Chain
    • Abstract: Kun Yang, Domenic Forte, Mark M. Tehranipoor

      The Internet of Things (IoT) is transforming the way we live and work by increasing the connectedness of people and things on a scale that was once unimaginable. However, the vulnerabilities in the IoT supply chain have raised serious concerns about the security and trustworthiness of IoT devices and components within them. Testing for device provenance, detection of counterfeit integrated circuits (ICs) and systems, and traceability of IoT devices are challenging issues to address. In this article, we develop a novel radio-frequency identification (RFID)-based system suitable for counterfeit detection, traceability, and authentication in the IoT supply chain called CDTA. CDTA is composed of different types of on-chip sensors and in-system structures that collect necessary information to detect multiple counterfeit IC types (recycled, cloned, etc.)

  • Application-Specific Residential Microgrid Design Methodology
    • Abstract: Korosh Vatanparvar, Mohammad Abdullah Al Faruque

      In power systems, the traditional, non-interactive, and manually controlled power grid has been transformed to a cyber-dominated smart grid. This cyber-physical integration has provided the smart grid with communication, monitoring, computation, and controlling capabilities to improve its reliability, energy efficiency, and flexibility. A microgrid is a localized and semi-autonomous group of smart energy systems that utilizes the above-mentioned capabilities to drive modern technologies such as electric vehicle charging, home energy management, and smart appliances. Design, upgrading, test, and verification of these microgrids can get too complicated to handle manually. The complexity is due to the wide range of solutions and components that are intended to address the microgrid problems.

  • Low-Power Clock Tree Synthesis for 3D-ICs
    • Abstract: Tiantao Lu, Ankur Srivastava

      We propose efficient algorithms to construct a low-power clock tree for through-silicon-via (TSV)-based 3D-ICs. We use shutdown gates to save clock trees’ dynamic power, which selectively turn off certain clock tree branches to avoid unnecessary clock activities when the modules in these tree branches are inactive. While this clock gating technique has been extensively studied in 2D circuits, its application in 3D-ICs is unclear. In 3D-ICs, a shutdown gate is connected to a control signal unit through control TSVs, which may cause placement conflicts with existing clock TSVs in the layout due to TSV’s large physical dimension. We develop a two-phase clock tree synthesis design flow for 3D-ICs: (1) 3D abstract clock tree generation based on K-means clustering and (2) clock tree embedding with simultaneous shutdown gates’ insertion based on simulated annealing (SA) and a force-directed TSV placer.

  • PeaPaw: Performance and Energy-Aware Partitioning of Workload on
           Heterogeneous Platforms
    • Abstract: Li Tang, Richard F. Barrett, Jeanine Cook, X. Sharon Hu

      Performance and energy are two major concerns for application development on heterogeneous platforms. It is challenging for application developers to fully exploit the performance/energy potential of heterogeneous platforms. One reason is the lack of reliable prediction of the system’s performance/energy before application implementation. Another reason is that a heterogeneous platform presents a large design space for workload partitioning between different processors. To reduce such development cost, this article proposes a framework, PeaPaw, to assist application developers to identify a workload partition (WP) that has high potential leading to high performance or energy efficiency before actual implementation. The PeaPaw framework includes both analytical performance/energy models and two sets of workload partitioning guidelines.

  • Layer Assignment of Escape Buses with Consecutive Constraints in PCB
    • Abstract: Jin-Tai Yan

      It is important for cost and reliability consideration to minimize the number of the used layers in a PCB design. In this article, given a set of n circular escape buses with their escape directions between two adjacent components and a set of m consecutive constraints on the escape buses, the problem of assigning the given escape buses between two adjacent components onto the minimized layers is first formulated for bus-oriented escape routing. Furthermore, an efficient approach is proposed to minimize the number of the used layers for the given escape buses with the consecutive constraints and assign the escape buses onto the available layers.

      To alleviate high energy dissipation of unnecessary snooping accesses, snoop filters have been designed to reduce snoop lookups. These filters have the problem of decreasing filtering efficiency, and thus usually rely on partial or whole filter reset by detecting block evictions. Unfortunately, the reset conditions occur infrequently or unevenly (called passive filter deletion). This work proposes the concept of revitalized snoop filter (RSF) design, which can actively renew the destination filter by employing a generation wrapping-around scheme for various reference behaviors. We further utilize a sampling mechanism for RSF to timely trigger precise filter revitalizations, so that unnecessary RSF flushing can be minimized.

  • Topological Approach to Automatic Symbolic Macromodel Generation for
           Analog Integrated Circuits
    • Abstract: Guoyong Shi, Hanbin Hu, Shuwen Deng

      In the field of analog integrated circuit (IC) design, small-signal macromodels play indispensable roles for developing design insight and sizing reference. However, the subject of automatically generating symbolic low-order macromodels in human readable circuit form has not been well studied. Traditionally, work has been published on reducing full-scale symbolic transfer functions to simpler forms but without the guarantee of interpretability. On the other hand, methodologies developed for interconnect circuits (mainly resistor-capacitor-inductor (RCL) networks) are not suitable for analog ICs. In this work, a topological reduction method is introduced that is able to automatically generate interpretable macromodel circuits in symbolic form; that is, the circuit elements in the compact model maintain analytical relations of the parameters of the original full circuit.
