Abstract
A monolithic high performance processor for computing digital signal processing algorithms based on the Fast Fourier Transform. The monolithic processor employs an array of bit-serial multipliers which cooperate with bit-serial adder/substractors to produce fast results with great precision, with reduced printed-circuit board space, and with low power requirements. The processor uses local asynchronous control and simple interfacing with the host computer. The processor, which is applicable to a broad spectrum of digital signal processing, including digital audio, radar/sonar, seismic and speech processing, operates in a variety of modes which allow the device to perform Fast Fourier Transforms, Inverse Fast Fourier Transforms, windowing, multiplication, Finite Impulse Response filtering, convolution and correlation.
