摘要

一个通用的DSP电路执行预编程功能，如256点FFT在500μs在400μs以下将被描述。该装置的收缩阵列可以在500μs内完成1024点的FFT。155K晶体管芯片采用1.25μm CMOS，在66.9mm2的芯片面积上制成，工作频率为12MHz。

A programmable signal processor for array applications

A general purpose DSP circuit performing pre-programmed functions such as a 256 point FFT in 500μs in under 400μs will be described. Systolic arrays of the device can perform a 1024-point FFT in 500μs. A 155K transistor chip has been fabricated in 1.25μm CMOS on a die area of 66.9mm2, and operates at 12MHz.
