    • An information handling system includes a multi-core processor that processes variable-length code (VLC) bitstream data. The bitstream data includes multiple codewords for interpretation. The processor includes a general purpose unit (GPU) and a special purpose unit (SPU). The GPU includes GPU buffers and the SPU includes SPU buffers. After populating one GPU buffer with bitstream data, the processor populates another GPU buffer with subsequent bitstream data. The processor may populate the GPU buffers in alternating fashion. The processor populates one SPU buffer with bitstream data while parsing bitstream data in the other SPU buffer. The GPU of the processor populates the SPU buffers in alternating fashion. The size of the GPU buffers may be a multiple of the size of the SPU buffers. After the SPU buffers consume the bitstream data from one GPU buffer, the other GPU buffer transfers its bitstream data to the SPU buffers for parsing.

    • A method for enabling a MIMO operation mode in a multimode communication terminal includes switching a first channel module to have parameter characteristics consistent with those of a second channel module, so that the multimode communication terminal enables the MIMO operation mode by using the first channel module and the second channel module at the same time. The method also includes extracting corresponding parameters from the second channel module and configuring the first channel module to be switched with the extracted parameters, such that the first channel module and second channel module enable the multimode communication terminal to perform MIMO communication. The method further includes issuing, upon determination of a switch, notification instructions to means in channel switch layer means and changing a data channel associated with the first channel module, such that the first channel module and second channel module can be adapted to the MIMO operation mode.
