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.
