Abstract
PURPOSE: To speed up the branch instruction processing without causing the competition with the main stream instruction for the processing due to advanced instruction for branch, by interpreting the branch instruction advanced independently of normal instruction processing and performing address calculation.
CONSTITUTION: The memory unit control S 1 controls the access to the memory unit by the instruction control I unit(consisting of B,O subunits) or the operation E unit 3. Althought the branch instruction can be picked up from the instruction in the buffer in the B subunit, this branch instruction is entirely independently picked up from the normal sequence of instruction processing fed to the unit 13 with the bus 14 and is fed to the unit 13 with the bus 15. Next, the unit 13 interpretes the branch instruction fed from the bus 15 entirely independently of the interpretation and address calculation of instruction fed with the bus 14, calculates the branched address, and the branched address obtained is fed to the unit 12 with the bus 16.
