  • Device for decoding signals of the MPEG-type
    Patent number: 5872577
    Abstract: The invention relates to a device for decoding encoded digital signals of the MPEG-type, comprising different modules (M1, M2, M3, . . . ), provided for communicating with an external random-access memory via an arbiter (ARB) intended to control the different types of access. Storage in the memory and the method of addressing are such that the decoding operation may not only be carried out with a conventional memory (DRAM) but also with synchronous DRAM memories (SDRAM), in which the arbiter uses the same mode of communication in each case and the other modules remain unchanged.
