Patent ID: 6957179

Claim:
A method of communicating with an integrated circuit chip having plural components thereon, said components including digital processing circuitry and an on-chip emulator connected to said digital processing circuitry for initiating command and control sequences for the digital processing circuitry in response to externally applied signals or in response to detected states of the digital processing circuitry, the method comprising: providing universal serial bus having first and second ends, said first end being connected to said on-chip emulator; providing a computer device having a digital processor, a universal serial bus port connected to said second end of said universal serial bus, and a second port for connection to a communication channel; assigning at least one of said components with a respective address; sending a remote procedure call from said component over said universal serial bus to said computer device, said remote procedure call including data indicative of the address of said component; in response thereto, causing said computer device to generate a socket call over said communication channel thereby creating a first socket at said computer device and a second socket at a computer connected to said communication channel; in said computer device, receiving a response at said first socket; and sending information derived from said response over said universal serial bus to said component.
