Title: Digital data processing apparatus

Filed: 1975-10-03
Abstract: 1475849 Program branching INTERNATIONAL BUSINESS MACHINES CORP 3 Oct 1975 [4 Dec 1974] 40466/75 Heading G4A In a system in which each instruction fetch cycle extends over a plurality of time periods (instruction fetch and execution cycles may be overlapped), the address of a branch-to instruction is formed during the execution of a branch instruction and the first time period of the instruction fetch cycle for the branch-to instruction is skipped. Normally the contents of an address register in a stack LSR (there may be one for each program/interrupt level) are loaded into a storage address register SAR and an X register at T0 time of a fetch cycle. During T1 and T2 of the fetch cycle the address is incremented and loaded into the address register (LSR) before the start of the execution cycle at T3 time. In the case of an unconditional branch instruction, the branch-to address is formed during T3 by gating, 80, to the SAR and X registers, bits 0-3 from the X-register and bits 4-15 from the storage data register SDR which contains bits of the branch instruction. A conditional branch instruction which is met (decode 180) causes modification of the storage gate selection by decode 60 so that the branch-to address is formed during T3 time from bits 0-7 from the address register (LSR) and bits 8-15 from SDR i.e. from the branchon-condition instruction. In the case of a non- satisfied branch-on-condition instruction-the next address is obtained wholly from the address register i.e. the incremented address is used. The recognition, during T3 time, of the presence of a branch or branch-on-condition instruction in the instruction register IR causes decode logic 50 to generate an ADVANCE CLOCK signal so that the next clock state is time T1 i.e. the second time period of the fetch cycle for the branch-to instruction.
