Definitions of annulled branch words
- abbreviation Technical meaning of ANNULLED BRANCH delayed control-transfer 3
- noun Definition of annulled branch in Technology (architecture) A technique used on the SPARC processor to reduce the effect of pipeline breaks by executing the instruction after a branch instruction (the "delay instruction" in the "delay slot"). If there is no useful instruction which can be placed in the delay slot then the "annul bit" on the control transfer instruction can be set, preventing execution of the delay instruction (unless the control transfer is conditional and is taken). Annulled branches are indicated in SPARC assembler language by appending ",A" to the operation code. For example, LOOP: ... CMP %L0,10 BLE,A LOOP ADD %L2, %L3, #L4 If the delay instruction is also a control transfer instruction then it gets more complicated. Both control transfer instructions are executed (but not the following instruction) and, assuming they are both taken, control is transferred briefly to the destination of the first and then immediately to the destination of the second. 1
