Abstract
An apparatus and method are disclosed to implement digital signal processing operations involving multiply-accumulate (MAC) operations, by using a modified balanced data structure and accessing architecture. This architecture maintains a data-path connecting one address generation unit, one register file and one MAC execution unit. The register file has a hierarchical grouping organization of individual registers, which reduces bubble cycles caused by memory misalignments. This architecture uses parallel execution and can achieve two or more MAC operations per cycle.
