Registers 32a-32d hold data for pixels interleaved. An operator 34 reads the pixel data from the registers and processes the pixel data in accordance with a program code. The operator 34 writes the result of the process back to the registers via a cache 38 or writes it in a memory. Program counters PC0-PC3 provided in association with the number of pixels interleaved store the addresses of instructions in a program for the respective pixels. An instruction loader 76 alternately reads from the program counters. An incrementer 74 increments the count of the program counters. The instructions in the program for the pixels are alternately loaded and interleaved on a pixel by pixel basis, before being supplied to the operator 34 and the like.
