Abstract
A method is provided for estimating statistics of properties of instructions processed in a pipeline of a computer system, the pipeline having a plurality of processing stages. Instructions are fetched into a first stage of the pipeline. Some of the fetched instructions are randomly selected. State information of the system is recorded in a profile record as samples while the selected instruction are processed by the pipeline. The recorded state information is communiucated to software. The software statistically analyzes the recorded state information from a subset of the selected instructions to estimate the statistics of the instructions.
