Abstract
An apparatus for sampling states of a computer system having a hierarchical memory arranged at a plurality of levels, the hierarchical memory storing data at addresses. The apparatus includes a selector for selecting memory transactions based on first state and transaction information. The memory transactions are to be processed by the hierarchical memory. A trigger activates the selector based on second state and transaction information. A sampler stores states of the computer system that are identified with the selected instructions while processing the selected memory transactions in the hierarchical memory.
