  • MPEG decoder system and method having a unified memory for transport decode and system controller functions
    Patent number: 5870087
    Abstract: An MPEG decoder system and method for performing video decoding or decompression which includes a unified memory for multiple functions according to the present invention. The video decoding system includes transport logic, a system controller, and MPEG decoder logic. The video decoding system of the present invention includes a single unified memory which stores code and data for the transport, system controller and MPEG decoder functions. The single unified memory is preferably a 16 Mbit memory. The MPEG decoder logic includes a memory controller which couples to the single unified memory, and each of the transport logic, system controller and MPEG decoder logic access the single unified memory through the memory controller. The video decoding system implements various frame memory saving schemes, such as compression or dynamic allocation, to more efficiently use the memory.
