Abstract
Techniques are disclosed relating to using non-debug path circuitry to perform debug commands. In some embodiments, an apparatus includes a processor core that includes path circuitry configured to access data for instructions executed by the processor core and storage elements which the path circuitry is configured to access via one or more ports. In some embodiments, the apparatus includes debug circuitry configured to receive external debug inputs and send abstract commands to the processor core based on the external debug inputs. In some embodiments, the apparatus includes control circuitry in the processor core configured to, in response to an abstract command to access one or more of the storage elements: generate signaling to access the one or more storage elements using the path circuitry, access read data from the one or more storage elements based on the signaling, and transmit the accessed read data to the debug circuitry.
