Abstract
A computer system and method for transferring data from a first memory to a second memory of a computer system are disclosed. The computer system includes a bus for transferring data between a first module and a second module, at least one of the modules including a shared memory having multiple ports. One port of each shared memory communicates with the bus through a pipeline which includes a plurality of registers connected in series. The pipeline allows shifting data in the registers by one register and loading data from the input of the pipeline into a first one of the registers. An access to one of the shared memories through one port is allowed to proceed simultaneously with a portion of a data transfer between the memories which includes a data transfer through another port and pipeline. The pipelines thus allow shared memories to communicate even when the memories are not simultaneously available for communication with each other.
