    This paper describes a VLSI implementation of an array processor for 16-point FFT computation, which consists of 16 processing elements(PEs) working in parallel. Design considerations both in chip level and in PE level have been examined in order to optimize the performance of the array processor. Layout design methodology based on Bit-Slice-Unit(BSU) results in a very fast design and easy debugging, as well as a regular interconnection scheme through abutment. The chip contains about 48,000 transistors and 83 pads on an area of 8.8×8.7 mm². It has been fabricated with a 2 µm, double -metal, P-well CMOS technology. Based on the measurement results, it is estimated that a 16-point FFT can be computed every 3 µsec, and the array processor can perform an equivalent of 24.6 million complex multiplications per second with a 15 MHz clock.
