摘要:
The present invention provides a method and apparatus for dynamically configuring debug triggering patterns. One example embodiment of the method includes comparing values of bits received on a first subset of a plurality of lines of a bus with a first pattern of bits and capturing values of bits received on a second subset of the plurality of lines of the bus in response to the comparison indicating that the values of the bits received on the first subset of the lines match the first pattern of bits. The exemplary embodiment of the method also includes defining a second pattern for triggering a debug action using the captured values.

An integrated circuit with debug capability includes a first packer and synchronizer to combine a multiple number of values of a first trigger signal received from a first circuit to form a first packed trigger signal and to output a synchronized first packed trigger signal in response to a trigger clock signal, the first trigger signal being synchronous with a first source clock signal, a first logic gate to provide a first output trigger signal indicative of whether any of the first multiple number of values of the first trigger signal in the first synchronized packed trigger signal is in a first state, and a debug state machine responsive to the first output trigger signal to selectively provide a first action signal.

摘要:
A method and apparatus for distributed on-chip debug triggering is presented. A first bus includes a plurality of lines and a debugging state machine configurable to monitor the plurality of lines of the first bus. One or more nodes are configurable to detect triggering events and provide, in response to detecting one or more triggering events, signals to the debugging state machine using a first subset of the plurality of lines that is allocated to the node(s).
摘要:
A system and method for efficiently debugging an integrated circuit with on-die hardware. A processor core includes an on-die debug state machine (DSM). The DSM includes multiple programmable storage elements for storing parameter values corresponding to multiple contexts. Each context is associated with a given one of multiple instruction sequences, such as at least threads and power-performance states. The DSM detects a sequence identifier (ID) and selects a context based on the sequence ID. The corresponding parameter values are used by transition conditions (triggers) and taken debug actions in a finite state machine (FSM) within the DSM. Each state and transition in the FSM is used by each one of the multiple contexts. The programmable DSM shares many resources, rather than replicating them, while being used for multiple sequences.
