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.
