Abstract
A Fast Walsh Transform (FWT) processor is disclosed, based on Good's factorization, which reduces the number of adder/subtractor units to (N/2), where N is the dimension of the FWT. The process time is equal to 2p clock cycles, where p=the 2's power of N. The clock period is determined by the delay times of the processor's internal devices (multiplexers, adder/subtractors, flip-flops), and can be minimized by using high speed complementary metal oxide semi-conductor (CMOS), or equivalent. The improvements in speed, and simplicity of implementation disclosed herein, offer performance and cost benefits in the field of digital cordless telephone technology.
