Abstract: A memory control and management system efficiently multiplexes access to a dynamic random access memory (DRAM) among several client processes in an MPEG or similar digital television delivery system or the like. These processes can include, for example, an on-screen display (OSD) graphics processor, a microprocessor interface, graphics accelerator functions, and audio and data processors. An arbiter receives packetized data from an MPEG transport layer for distribution to an associated DRAM. The arbiter sequentially time-multiplexes access to the DRAM by the client processes according to priority criteria, including the bandwidth requirements of the client processes, and whether a client process is requesting access. Access is granted for a predetermined period as long as the client is requesting access.
