Abstract
PURPOSE: To shorten the time of instruction execution of a computer which performs pipeline processing, by deciding on an execution address and setting a memory start signal in an early stage by only a specific instruction, and by reducing the memory access time load on this instruction within its execution time.
CONSTITUTION: Main memory unit 1 is brought under the control of main control unit 2 to transfer data to I-UNIT3 and E-UNIT4. Here, I-UNIT3 consists of instruction decoding unit 6 which generates a microprogram initial address in instruction execution and execution-address arithmetic unit 5 which calculates the execution-address. Then, E-UNIT4 consists of instruction execution unit 7 which executes actual instructions on the basis of the above-mentioned data transferred from I-UNIT3. Further, E-UNIT4 and I-UNIT3 are synchronized with each other through pipeline control unit 8, and the synchronization of the processing is put into effect on the end of each unit.
