Functional Constraint Extraction From Register Transfer Level for ATPG

  The use of scan test patterns, generated at the gate level with automatic test pattern generation (ATPG) tools in design simulation, was proposed in our previous work to improve verification quality. A drawback of this method is the potential presence of illegal (or unreachable) states (ISEs) causing unwanted behavior and false error detection in [...]

Z-TCAM: An SRAM-based Architecture for TCAM

  Ternary content addressable memories (TCAMs) perform high-speed lookup operation but when compared with static random access memories (SRAMs), TCAMs have certain limitations such as low storage density, relatively slow access time, low scalability, complex circuitry, and are very expensive. Thus, can we use the benefits of SRAM by configuring it (with additional logic) to [...]

Task Migrations for Distributed Thermal Management Considering Transient Effects

In this brief, a new distributed thermal management scheme using task migrations based on a new temperature metric called effective initial temperature is proposed to reduce the on-chip temperature variance and the occurrence of hot spots for many-core microprocessors. The new temperature metric derived from frequency domain moment matching technique incorporates both initial temperature and [...]

Energy Aware Mapping for Reconfigurable Wireless MPSoCs

    Energy management for multimode software defined radio systems remains a daunting challenge. This brief develops a high level framework that generates a multiprocessor systems on chip architecture from a library of heterogeneous processing resources that can be reconfigured to support various modes of operation. The framework proposes joint task and core mapping with [...]

Fault Tolerant Parallel Filters Based on Error Correction Codes

  Digital filters are widely used in signal processing and communication systems. In some cases, the reliability of those systems is critical, and fault tolerant filter implementations are needed. Over the years, many techniques that exploit the filters’ structure and properties to achieve fault tolerance have been proposed. As technology scales, it enables more complex [...]

Fast Sign Detection Algorithm for the RNS Moduli Set {2^{n+1}-1, 2^{n}-1, 2^{n}}

This brief presents a fast sign detection algorithm for the residue number system moduli set {2n+1 - 1, 2n- 1, 2n}. First, a sign detection algorithm for the restricted moduli set is described. The new algorithm allows for parallel implementation and consists exclusively of modulo 2n additions. Then, a sign detection unit for the moduli set {2n+1 - [...]

An 8 bit 0.3–0.8 V 0.2–40 MS/s 2-bit/Step SAR ADC With Successively Activated Threshold Configuring Comparators in 40 nm CMOS

A 0.3-0.8 V low-power 2-bit/step asynchronous successive approximation register analog-to-digital converter (ADC) is presented. A low-power 2-bit/step operation technique is proposed which uses dynamic threshold configuring comparator instead of multiple digital-to-analog converters (DACs). Power and area overhead is minimized by successively activated comparators. The comparator threshold is configured by simple Vcm biased current source, which [...]

Built-In Self-Test of Transmitter I/Q Mismatch and Nonlinearity Using Self-Mixing Envelope Detector

  Built-in self-test (BiST) for transmitters is a desirable choice since it eliminates the reliance on expensive instrumentation to perform radio-frequency signal analysis. Existing on-chip resources, such as power or envelope detectors or small additional circuitry, can be used for BiST purposes. However, due to limited bandwidth, measurement of complex specifications, such as in-phase and [...]

DScanPUF: A Delay-Based Physical Unclonable Function Built Into Scan Chain

Physical unclonable function (PUF) has emerged as an attractive primitive to address diverse hardware security issues in integrated circuits, such as authentication and cryptographic key generation. Most of the existing PUFs rely on dedicated circuit structure for generating random signatures. It often causes concerns due to extra design efforts and hardware overhead. Moreover, the hardware complexity increases [...]

A Report to the U.S. DOE: IEEE Shares Its Insights on Priority Issues

  UU.S. President Obama issued a presidential memorandum in January 2014 directing several federal agencies to undertake a quadrennial energy review (QER ), the first of which focuses on the development of a comprehensive strategy for the infrastructure involved in transporting, transmitting, and delivering energy, and report back in January 2015. The U.S. Department of [...]
