CROSS-TRIGGERING OF PROCESSING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a scalable interconnection system of a multiple processor system, which facilitates diagnostic cross-triggering of events between different processors in a stage of product development and to especially provide capabilities of achieving synchronous stop/start and steps of a plurality of cores in a single integrated circuit. SOLUTION: A data processing apparatus comprises a routing module which has a plurality of broadcast channels out of which one or more broadcast channels are operable to indicate the occurrence of a diagnostic event on one or more of the plurality of processing apparatuses. An interface module asserts diagnostic event signals from an associated processing apparatus to one or more of the plurality of broadcast channels and retrieves diagnostic event signals from processing apparatus other than the associated processing apparatus from one or more of the plurality of broadcast channels. The retrieved diagnostic event data is used to facilitate triggering of a diagnostic process on the associated processing apparatus, which is dependent upon the retrieved diagnostic event data.
