Abstract
Apparatus and method for a modified, balanced throughput data-path architecture is given for efficiently implementing the digital signal processing algorithms of filtering, convolution and correlation in computer hardware, in which both data and coefficient buffers can be implemented as sliding windows. This architecture uses a multiplexer and a data path branch from the Address Generator unit to the multiply-accumulate execution unit. By selecting between the data path of Address Generator to execution unit and the data path of register to execution unit, the unbalanced throughput and multiply-accumulate bubble cycles caused by misaligned addressing on coefficients can be overcome. The modified balanced throughput data-path architecture can achieve a high multiply-accumulate operation rate per cycle in implementing digital signal processing algorithms.
