ABSTRACT:
There is disclosed a method of communicating with an integrated circuit chip having plural components thereon, the components including digital processing circuitry and an on-chip emulator connected to the 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 of providing a universal serial bus having first and second ends, the first end being connected to the on-chip emulator; providing a computer device having a digital processor, a universal serial bus port connected to the second end of the universal serial bus, and a second port for connection to a communication channel; assigning at least one of the components with a respective address; sending a remote procedure call from the component over the universal serial bus to the computer device, the remote procedure call including data indicative of the address of the component; in response thereto, causing the computer device to generate a socket call over the communication channel thereby creating a first socket at the computer device and a second socket at a computer connected to the communication channel; in the computer device, receiving a response at the first socket; and sending information derived from the response over the universal serial bus to the component.
