    Abstract: A method for executing different sets of instructions that cause a processor to perform different data type operations in a manner that is invisible to various operating system techniques, that promotes good programming practices, and that is invisible to existing software conventions. According to one aspect of the invention, a data processing apparatus executes a first set of instructions of a first instruction type on what at least logically appears to software as a single logical register file. While the data processing apparatus is executing the first set of instructions, the single logical register file appears to be operated as a flat register file. In addition, the data processing apparatus executes a first instruction of a second instruction type using the logical register file. However, while the data processing apparatus is executing the first instruction, the logical register file appears to be operated as a stack referenced register file. Furthermore, the data processing apparatus alters all tags in a set of tags corresponding to the single logical register file to a non-empty state sometime between starting the execution of the first set of instructions and completing the execution of the first instruction. The tags identifying whether registers in the single logical register file are empty or non-empty.

    Abstract: A processor. The processor includes a decoder being coupled to receive a control signal. The control signal has a first source address, a second source address, a destination address, and an operation field. The first source address corresponds to a first location. The second source address corresponds to a second location. The destination address corresponds to a third location. The operation field indicates that a type of packed data shift operation is to be performed. The processor further includes a circuit being coupled to the decoder. The circuit is for shifting a first packed data being stored at the first location by a value being stored at the second location. The circuit is further for communicating a corresponding result packed data to the third location.

    Abstract: An apparatus comprising: a first storage area operable to have stored therein a first packed data containing at least an A 1 , an A 2 , an A 3 , and an A 4 element; a second storage area operable to have stored therein a second packed data containing at least a B 1 , a B 2 , a B 3 , and a B 4 element; a multiply circuit including a first multiplier coupled to said first storage area to receive said A 1 and coupled to said second storage area to receive said B 1 ; a second multiplier coupled to said first storage area to receive said A 2 and coupled to said second storage are to receive said B 2 ; a third multiplier coupled to said first storage area to receive said A 3 and coupled to said second storage area to receive said B 3 ; a fourth multiplier coupled to said first storage area to receive said A 4 and coupled to said second storage area to receive said B 4 ; a first adder coupled to said first multiplier and said second multiplier; a second adder coupled to said third multiplier and said fourth multiplier; and a third storage area coupled to said first adder and said second adder, said third storage area having at least a first field and a second field, said first field for saving an output of said first adder as a first data element of a third packed data, said second field for saving an output of said second adder as a second data element of said third packed data.

    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.\!
