摘要

在本文中,我们研究了128点FFT/IFFT处理器中异步(async)逻辑相对于同步(sync)逻辑的能量效率,用于低电压(1.1V至1.4V)能量关键的中低速应用,包括助听器。异步和同步设计都使用相同的工艺(0.35μm CMOS)实现,并且具有相同的计算复杂度。对于后一种同步设计,我们考虑了使用和不使用时钟门控方法的两种情况。与采用时钟门控方法和不采用时钟门控方法的同步设计相比,我们的异步设计的能耗分别降低了23%和39%。

A Low-Energy Asynchronous FFT/IFFT Processor for Hearing Aid Applications
In this paper, we investigate the energy efficacy of the asynchronous (async) logic over its synchronous (sync) counterpart in a 128-point FFT/IFFT processor for low voltage (1.1V to 1.4V) energy-critical medium-to-low speed applications including hearing aids. Both async and sync designs are implemented using the same process (0.35μm CMOS) and having the same computational complexity. For the latter sync design, we consider both scenarios with and without the clock gating approach. Our async design features ∼23% and ∼39% lower energy compared to its sync counterpart with and without the clock gating approach respectively.
