  • Single chip frame buffer and graphics accelerator
    Patent number: RE37944
    Abstract: A single chip display processor comprised of a dynamic random access memory (DRAM) for storing at least one of graphics and video pixel data, a pixel data unit (PDU) for processing the pixel data, integrated in the same integrated circuit (IC) chip as the DRAM, the IC chip further comprising a massively parallel bus for transferring blocks of pixel data at the same time from the DRAM to the PDU, whereby the PDU can process the blocks of pixel data for subsequent display of processed pixel data.
    Type: Grant
