A method for decompressing compressed data elements, drawing that decompression operation, the intermediate coefficients are organized in a matrix configuration such that the number of transpose operations are minimized. The organization of that matrix includes storing sequential coefficients, translated from the compressed data, in sequential locations of sequential columns of the matrix. The transpose operation is performed during the inverse discrete cosine operation portion of the decompression operation.

Method and apparatus for configuring compressed data coefficients to minimize transpose operations

In accordance with the present invention, a method and apparatus are provided for efficiently transmitting data between stages of a decompression pipeline by implementing a control store register for minimizing the amount of data that is transferred among decompression units. The control store register is a register having memory locations that are associated with decompressed coefficients. As the coefficients are decompressed, a determination is made as to whether they contain zero or non-zero values. The result of that determination is stored in the control store register such that the processor performing the inverse quantization and inverse discrete cosine operations only retrieves non-zero coefficients. Therefore, data transmission is performed in an efficient manner.
