    Abstract: A computer system for processing multimedia data, wherein the data is transformed from a first domain to a second domain by performing two dimensional rotation on the data. The computer system includes a memory having stored therein a set of packed data sequences having data elements representing the digital data, and a sequence of instructions for transforming the digital data from a first domain to a second domain. The instructions, when executed, cause the processor to generate a first set of intermediate results in response to the execution of a first instruction which multiples data elements of a first packed data sequence with corresponding elements of a third packed data sequence, wherein the data elements of the third packed data sequence represent either a sine or cosine function. The instructions then cause the processor to generate a second set of intermediate results in response to the execution of a second instruction which multiplies the data elements of a second packed data sequence with corresponding data elements of a fourth packed data sequence, wherein the data elements of the fourth packed data sequence representing either a sine or cosine function. A set of first set of final results is generated in response to the execution of a third instruction which performs an arithmetic operation between corresponding data elements of the first and second sets of intermediate results. The final results represent the digital data transformed into the second domain.

    Abstract: A computer system which manipulates audio and video signals. A multimedia input device which generates an audio and/or video signal is coupled to a processor. The processor is also coupled to a storage device upon which a decompression routine is stored, the decompression routine including a transposition routine. The transposition routine manipulates data elements associated with the audio or video signal in transposing an array of n rows of a plurality of data elements. The transposition routine causes the processor to interleave data elements from a first row with data elements from a second row to generate a first result. Data elements from a third row are interleaved with data elements from a fourth row to generate a second result. Then, data elements from the first result are interleaved with data elements from the second result to generate a third result.\!

    Abstract: A method and apparatus for performing complex digital filters. According to one aspect of the invention, a computer system generally having a transmitting unit, a processor, and a storage device is described. The storage device is coupled to the processor and has stored therein a routine. When executed by the processor, the routine causes the processor to perform a digital filter on unfiltered data items using complex coefficients to generate an output data stream. Execution of the routine causes the processor to perform outer and inner loops. The outer loop steps through corresponding relationships between the complex coefficients and the unfiltered data items. Each of these corresponding relationships is used by the digital filter to generate the output data stream. The inner loop steps the complex coefficients. Within the inner loop, the unfiltered data item corresponding to the current complex coefficient is determined according to the current corresponding relationship. Then, in response to receiving an instruction, eight data elements are read and used to generate a currently calculated complex number. As a result of the manner in which these eight data elements are stored, the currently calculated complex number represents the product of the current complex coefficient and its corresponding unfiltered data item. The currently calculated complex number is then added to the current output packed data. As a result, the current output packed data stores the sum of the complex numbers generated in the current inner loop.
