(Or "pipeline stall") The delay caused on a
processor using pipelines when a transfer of control is
taken. Normally when a control-transfer instruction (a
branch, conditional branch, call or trap) is taken, any
following instructions which have been loaded into the
processor's
pipeline must be discarded or "flushed" and new
instructions loaded from the branch destination. This
introduces a delay before the processor can resume execution.
"
Delayed control-transfer" is a technique used to reduce
this effect.
