C952 Computer Architecture - Parallelism via
Instructions fully solved
Multiple Issue
A scheme whereby multiple instructions are launched in one clock cycle.
Static multiple issue
An approach to implementing a multiple-issue processor where many decisions are made by the
compiler before execution
Dynamic multiple issue
An approach to implementing a multiple issue processor where many decisions are made during
execution by the processor.
Issue slot
The position from which instructions could issue in a given clock cycle
Speculation
An approach whereby the compiler or processor guesses the outcome of an instruction to remove it
as a dependence in executing other instructions
Issue packet
The set of instructions that issues together in one clock cycle; the packet may be determined statically
by the compiler or dynamically by the processor.
Very Long Instruction Word (VLIW)
A style of instruction set architecture that launches many operations that are defined to be
independent in a single wide instruction, typically with many separate opcode fields.
Use latency
Number of clock cycles between a load instruction and an instruction that can use the result of the
load without stalling the pipeline.
Loop unrolling
A technique to get more performance from loops that access arrays, in which multiple copies of the
loop body are made and instructions from different iterations are scheduled together.
Antidependence
Also called name dependence. An ordering forced by the reuse of a name, typically a register, rather
than by a true dependence that carries a value between two instructions.
Superscalar
An advanced pipelining technique that enables the processor to execute more than one instruction
per clock cycle by selecting them during execution.
Dynamic Pipeline Scheduling
