RESIDUE ARITHMETIC FOR REAL-TIME APPLICATIONS: HIGH THROUGHPUT AND RELIABILITY USING CUSTOMIZED MODULES.

Special-purpose processors for computation-intensive applications may be constructed using a single VLSI module type. Such a module has been designed and fabricated for implementation of finite-duration impulse response (FIR) filter structures. Residue arithmetic allows computation to be partitioned among several modules operating in parallel. Each module integrates both logic and high-density storage. Arithmetic functions are evaluated by reading precomputed values from stored tables that are customized for each module. Error detection/correction and fault isolation are supported at module boundaries.
