Abstract

An efficient hardware implementation of a 1024-point sequential FFT processor is described. The processor has been configured in a distributed processing system with an INTEL 8086 microprocessor. In case of real signals, it performs a 1024-point transform of two real signals, simultaneously within the same period and subsequently does spectral separation 2.6 msec. Its general purpose capability and the case of interfacing it with standard mini/micro computers are highlighted with a specific illustrations using the INTEL 8086 microprocessor.
