摘要： A processor or an integrated circuit chip including a debug state machine (DSM) that allows for programming complex triggering sequences for flexible and efficient debug visibility is disclosed. The DSM centralizes control of local debug functions such as trace start and stop, trace filtering, cross triggering between DSMs, clock stopping, triggering a system debug mode interrupt, flexible microcode interface, and the like. The DSM is configured to receive triggers from a processor core, other DSMs, a northbridge, other sockets, and the like and initiate a programmed action on a condition that a corresponding trigger or a sequence of triggers occurs.
