Abstract

A highly intelligent programmable multi-tasking memory management system manages memory requests associated with a system on chip (SOC) device. The memory management system includes a routing controller or central processing unit (RCPU) that is used for routing/switching stream data between communication cores and digital signal processors with minimum reliance and demand on a main or virtual central processing unit (VCPU) residing on a system bus. Tasks are partitioned between the VCPU and the RCPU within the SOC architecture for communication applications. The VCPU performs system/application tasks while the RCPU simultaneously performs multiple memory routing/switching tasks and multiple concurrent memory access connections. The memory management system also enables other processors and communication cores to update their internal data once new data is written in the memory system. In addition, a method and system are provided for performing predictive protocol fetch for multiple DSPs on the SOC to increase data processing throughput.
