摘要

我们提出了一种用于低功耗M2M通信的异步(QDI) FFT设计。该设计通过具有高效的内存控制、旋转乘法以及允许这个嵌套蝴蝶架构中的所有子系统只按照它们需要的速度运行来实现低功耗。对于10MHz输入数据速率，我们的128点，16位，基数23 FFT设计在Vdd=1V的65nm技术下仅消耗5.9nJ的能量。

Low Power QDI Asynchronous FFT

We present an asynchronous (QDI) FFT design for low-power M2M communication. The design achieves low power by having efficient memory controls, twiddle multiplication, and allowing all subsystems in this nested butterfly architecture to run only as fast as they need to run. For a 10MHz input data rate, our 128-point, 16-bit, radix-23 FFT design consumes only 5.9nJ of energy at Vdd=1V in a 65nm technology.
