Instruction Level Parallelism (ILP) - Auburn University
Instruction Level Parallelism (ILP) Colin Stevens What is a parallel instruction? ILP is a measure of the number of instructions that can be performed during a single clock cycle. Parallel instructions are a set of instructions that do not depend on each other to be executed. Hierarchy Bit level Parallelism
16 bit add on 8 bit processor Instruction level Parallelism Loop level Parallelism for (i=1; i<=1000; i= i+1) x[i] = x[i] + y[i]; Thread level Parallelism (SMT, multi-core computers) Making Computers Think Parallel Human Write code yourself, directly controlling each processor Compiler
