Abstract: 
The instruction level parallelism (ILP) of an application is a measure of how many machine instructions can potentially be issued per cycle when the application is executed; it is a key determinant of execution time of an application on a multiple-issue architecture. We will describe simulation-based studies of various programs: selected benchmarks from the SPECint95 suite, Java applications from the SPECjvm98 suite, and multimedia applications from the Mediabench suite. The effect of hardware constraints such as lookahead window size, imperfect branch prediction using McFarling's gshare predictor and path history-based jump target prediction will be presented.
