Abstract
A signal processor includes one or more memory banks, wherein each memory bank stores filter coefficients; and one or more coefficient multiplexer units; each coefficient multiplexer unit being associated with a memory bank, and retrieves a filter coefficient based on a number of received input samples. The processor includes one or more multiply and accumulate (MAC) units, each MAC unit being associated with a coefficient multiplexer unit and determines a product of the retrieved filter coefficient with an input sample; retrieves a previous value stored in an associated register; computes a summation of the previous value and the product; and stores the summation in the associated register. The processor includes an output multiplexer unit to select a register, and to provide a value stored in the register as an output.
