Single-board digital signal processor

Hardware and software needed to implement a 16-bit microprocessor-based, single-board digital signal processing system are outlined and discussed. As described, the system can perform high-speed digital filtering and fast Fourier transforms in real time for signals of up to 35 kHz, and the basic architecture can be extended readily to handle higher frequency signals in real time. The system is built around a 2901B bit-slice microprocessor, two 2911 microcontrollers, a TRW 16-bit multiplier-accumulator, nine 512×8 registered PROMs, and twelve 1024×4 RAMs. Applications of this system to matrix multiplication and other matrix operations are also discussed.
