System signalling schemes for processor & memory module

摘要

A computer system includes a main processing unit (12) coupled to a DSP/memory module (40). The DSP/memory module (40) includes semiconductor memory (42) and digital signal processor circuitry (44) including one or more digital signal processors (56). The DSP/memory module (40) may be placed in standard main memory sockets, such as a SIMM or DIMM sockets, and used as conventional main memory. The memory module can also be used in a smart mode, wherein the digital signal processor (56) performs operations on data for retrieval by the main processing unit (12).
