Instruction Level Parallelism

We now concentrate on promoting instruction level parallelism (ILP) in order to further improve pipeline performance ILP: amount of parallelism in a basic block of code code without branches, or code between branches given that branches make up about 15%-25% of all code in our MIPS examples

Program Representations

Program Representations. Representing programs. Goals. Representing programs. Primary goals analysis is easy and effective just a few cases to handle directly link related things transformations are easy to perform general, across input languages and target machines Additional goals

Components of representation

Components of representation. Control dependencies: sequencing of operations evaluation of if & then side-effects of statements occur in right order Data dependencies: flow of definitions from defs to uses operands computed before operations

Representing programs

Representing programs. Goals. Representing programs. Primary goals analysis is easy and effective just a few cases to handle directly link related things transformations are easy to perform general, across input languages and target machines Additional goals compact in memory
