    Approximate computing is the idea that systems can gain performance and energy efficiency if they expend less effort on producing a “perfect” answer. Approximate computing techniques propose various ways of exposing and exploiting accuracy-efficiency tradeoffs. We present a taxonomy that classifies approximate computing techniques according to salient features: visibility, determinis... View full abstract»

    Approximate multiplication is a common operation used in approximate computing methods for high performance and low power computing. Power-efficient circuits for approximate multiplication can be realized with an approximate 4-2 compressor. This letter presents a novel design that uses a modification of a previous approximate 4-2 compressor design and adds an error recovery module. The proposed de... View full abstract»

  • A 64 kB Approximate SRAM Architecture for Low-Power Video Applications

    A voltage-scalable SRAM architecture suitable for video applications where energy can be traded with output signal quality is presented. The proposed 6T SRAM architecture uses three supply voltages to improve the static noise margin during read and write modes and also reduces leakage current in retention mode, hence, it allows aggressive supply voltage scaling for low power multimedia application...

    In this letter, we design a nonvolatile approximate lookup table, called Nvalt, to significantly accelerate general public utilities (GPUs) computation. Our design stores high frequency input patterns within an approximate Nvalt to model each application's functionality. Nvalt searches for and returns the stored data best matching the input data to produce an approximate output. We define a simila... View full abstract»

  • Data-Dependent Loop Approximations for Performance-Quality Driven High-Level Synthesis

    Publication Year: 2018, Page(s):18 - 21

    Approximate computing (AC) obtains performance or energy gains by trading off computational accuracy in error-tolerant applications. At the hardware level, AC-aware high-level synthesis tools apply operation-level approximations to generate a quality-reduced register-transfer level design from an accurate high-level description. While existing tools primarily target energy savings, we focus on per... View full abstract»

    Approximate computing (AC) is an emerging paradigm for energy-efficient computation. The basic idea of AC is to sacrifice high precision for low energy by allowing hardware to carry out “approximately correct” calculations. This provides a major challenge for software quality assurance: programs successfully verified to be correct might be erroneous on approximate hardware. In this l... View full abstract»

    As it becomes more and more evident that approximate computing (AC) is a key enabler for next-generation computer architectures, physical realization of AC systems is gaining in relevance. This letter discusses a crucial and under-investigated area: the relationship between hardware failures and the AC paradigm. We present the opportunities of efficient test methods to improve yields of hardware b... View full abstract»
