Video decoder with shared memory and methods for use therewith

摘要

A video decoder includes an entropy decoding device that includes a first processor that generates first entropy decoded (EDC) data from a first portion of an encoded video signal and further that generates second EDC data from a second portion of the encoded video signal. A general video decoding device includes a second processor that generates a first portion of a decoded video signal from the first EDC data and that further generates a second portion of the decoded video signal from the second EDC data. A shared memory includes at least one buffer that is accessed by the general video decoding device via absolute memory addressing.

1. A video decoder comprising:
an entropy decoding device that includes a first processor that generates first entropy decoded (EDC) data from a first portion of an encoded video signal and further that generates second EDC data from a second portion of the encoded video signal; a general video decoding device, coupled to the entropy decoding device, that includes a second processor that generates a first portion of a decoded video signal from the first EDC data and that further generates a second portion of the decoded video signal from the second EDC data; and a shared memory, coupled to the entropy decoding module and the general video decoding device, the shared memory including at least one buffer that includes at least three ports for contemporaneous access by the entropy decoding module, the general video decoding device and at least one application, wherein the shared memory is accessed by the general video decoding device via absolute memory addressing without requiring the at least one application to release the shared memory.
