  • Publication number: 20060067582
    Abstract: An apparatus and a method for efficient decoding progressive JPEG bitstreams are invented. This invention provides a memory-efficient progressive JPEG decoding method with minimal memory requirements. Instead of storing all the DCT coefficients of at particular decoding scan, a portion of DCT coefficients and the non-zero coefficient indicators for the rest of the DCT coefficients are stored in either original data format or in a compressed format. The memory requirement for decoding progressive JPEG pictures can be minimized according to the resolution of display devices in the real applications.

  • Publication number: 20020120709
    Abstract: With a shared common memory, internal requests of a multimedia processor (70) is processed to generate a request (140) optimized in format. Each internal request is selected by the request controller according to a system priority. Each of external requests is independently subjected to an analyzing process for each format adapter (160), and is converted into a format compatible with a predetermined internal format of the multimedia processor. Thus, one or more external processors share a common memory to enable the external processors to access a bulk memory storage of a multimedia processor.
