SINGLE-INSTRUCTION PLURAL-DATA PROCESSING FOR WHICH SCALAR/VECTOR OPERATION IS COMBINED

摘要

PROBLEM TO BE SOLVED: To improve the efficiency and speed of a program at the time of applying multi-media by providing a vector register or a scalar register as an operand and parallelly operating the multiple data elements of the vector register so as to improve calculation ability. SOLUTION: A multi-media processor 100 is provided with a processing core 105 provided with a general purpose processor 110 and a vector processor 120. The processing core 105 is connected to the remaining of the multi-media processor 100 through a cache sub system 130 provided with SRAMs 160 and 190, a ROM 170 and a cache control 180. The processor 100 is realized by using a general purpose processor architecture. In response to a signal instruction, the processing core 105 parallelly performs arithmetic operations for connecting one element among the data elements from the vector register and a scalar value from the scalar register for the respective arithmetic operations.
