Abstract
A computer system providing multiple processors or masters an architecture for highly concurrent processing and data throughput. A multiple channel memory architecture provides concurrent access to memory. Arbitration and snoop logic controls access to each memory channel and maintains cache coherency. A host CPU, multimedia processor, pipes processor and display controller may independently and concurrently access memory. The pipes processor provides a decoupled input/output processor for universal serial bus and firewire serial buses to free up the host CPU.
