Abstract

PURPOSE: To prevent micro steps from increasing in number by providing a data generation part that generates prescribed data according to the contents of a specific field in a micro instruction and by processing its output as an operand.
CONSTITUTION: In the information processor, data generation part 8 is provided which generates data pattern high in frequency of use and a data pattern used where the speed should not be reduced. Generation part 8 receives four bits of field S of micro instruction register 1 and generates a fixed corresponding 16-bit data pattern from the input code. One of registers in group 3 is selected corresponding to the code of field S. Decoder 9 generates detection signal 10 when field E register 1 has a prescribed value or nondetection signal 11 when not to open gate 8 or 13 and inputs 16-bit data from generation part 8 or register group 3 to operator 4, which processing it as an operand.
