multiple issues in computer architecture
There are two general approaches to multiple issue: static multiple issue (where the scheduling is done at compile time) and dynamic multiple issue (where the scheduling is done at execution time), also known as superscalar. Intel Core 2 processors are superscalar and can issue up to 4 instructions per clock cycle.
Instruction-level parallelism (ILP) is a measure of how many of the instructions in a computer The Pentium processor works on the dynamic sequence of parallel Instruction pipelining where the execution of multiple instructions can be
Multiple Issue CPUs. In contrast, VLIW (Very Long Instruction Word) processors issue a fixed number of instructions per clock.
Packages them into “issue slots". Compiler detects and avoids hazards. Dynamic multiple issue. CPU examines instruction stream and chooses instructions to
Hardware attempts to issue up to n instructions on every cycle, where n is called the issue width of the processor and the processor is said to have n issue slots
Multiple-Issue Processors can be: • Dynamically scheduled (issue a varying number of instructions at each clock cycle). • Statically scheduled (issue a fixed
Dual issue means that each clock cycle the processor can move two instructions from one stage of the pipeline to another. Where this happens
Multiple instructions issued each cycle. • a processor that can execute more than one instruction per cycle. • issue width = the number of issue slots, 1 slot/
A superscalar processor is a CPU that implements a form of parallelism called instruction-level Instructions are issued from a sequential instruction stream; The CPU dynamically checks for data dependencies But merely processing multiple instructions concurrently does not make an architecture superscalar, since
