Modified Memory Architecture for CODECS With Multiple CPUs

摘要

The solution proposed in this invention is a nearest neighborhood access protocol, where not every processor is given access to every other memory block. It is shown by analyzing the pipeline that it is adequate to have no more than two masters (CPU's) in particular and 3 CPU's in general. In the case of the 2 CPU approach one of these CPU's is a producer, and the other CPU is a consumer. In the 3 CPU case the third owner may be a DMA channel.
