SYSTEM-ON-CHIP, METHOD OF MANUFACTURE THEREOF AND METHOD OF COMMUNICATING DIAGNOSTIC DATA

摘要

A system-on-chip comprises an internal module having diagnostic functionality, and a physical communications port coupled to a first data path and arranged to support, when in use, a datagram-based communications interface for communicating with an external data communications unit. Debug logic circuitry is operably coupled to a debug interface and the internal module, the debug interface being arranged to support communication of debug data relating to the internal module. The system-on-chip also comprises configurable hardware logic circuitry configured as datagram processing logic and is arranged to support use of a datagram to communicate with the debug logic. The datagram processing logic is operably coupled to the first data path and a second data path, the second data path being operably coupled to the debug interface.
