PROGRAM PROCESSING SYSTEM

摘要

PURPOSE:To improve the using efficiency of a program memory as well as the processing speed by adding the arithmetic condition information to each instruction word of a program. CONSTITUTION:A CPU 1 reads an operating part OP1 out of a program memory 2 and fetches it to an arithmetic part 11 to check the arithmetic condition information 5A. If the information 5A is equal to 1, the CPU 1 reads again an operand 61 out of the memory 2 to write it to an operand information storage part 12 and executes the processing of the part OP1 read previously. Then an operating part OP2 is read out and the operand information is extracted out of the part 12 of the part 11 when the information 5A is equal to 0. Then the operand information is executed together with the contents of the OP2 fetched previously.
