基于传输触发结构的低功耗快速傅里叶变换可编程处理器

Low-power Programmable Processor for Fast Fourier Transform Based on Transport Triggered Architecture

Jakub Žádník, Jarmo Takala

摘要:

本文介绍了一种低功耗的处理器专为快速傅立叶变换计算的运输触发模板被利用。该处理器是软件可编程的,同时保持与现有固定功能实现相当的能效。通过将计算内核压缩成一个指令字来实现功率节省。该字存储在指令循环缓冲区中,这比常规指令存储器存储更节能。该处理器支持从64到16384的所有2的幂次FFT大小,并且给定1 mJ的能量,它可以计算20916个大小为1024的变换。

英文摘要:

This paper describes a low-power processor tailored for fast Fourier transform computations where transport triggering template is exploited. The processor is software-programmable while retaining an energy-efficiency comparable to existing fixed-function implementations. The power savings are achieved by compressing the computation kernel into one instruction word. The word is stored in an instruction loop buffer, which is more power-efficient than regular instruction memory storage. The processor supports all power-of-two FFT sizes from 64 to 16384 and given 1 mJ of energy, it can compute 20916 transforms of size 1024.
