Patent ID: 7058855

Claim:
An integrated circuit, comprising: at least one processor core; at least one processor emulator circuit coupled to the at least one processor core and operable to produce information indicative of process activity associated wit the at least one processor core; at least one other core; at least one other emulator circuit coupled to the at least one other core and operable to produce information indicative of process activity associated with the at least one other core; a single input/output port; and a single emulation interface circuit coupled to both the at least one processor emulator circuit and the at least one other emulator circuit and to said input/output port, said single emulation interface circuit operable to receive and compress the respective information indicative of the process activity associated with the at least one processor core and the at least one other core and to select portions of said information and transmit said selected portions through said single input/output port to one or more sources external to the integrated circuit, said single emulation interface circuit further operable to receive processor emulator control signals form said one or more sources external to said integrated circuit and transmit said control signals to said at least one processor emulator circuit and said at least one other emulator circuit.
