DIAGNOSTIC CONTEXT CONSTRUCTION AND COMPARISON

机译:诊断上下文的构建和比较

摘要

PPROBLEM TO BE SOLVED: To provide a data processing system providing a diagnostic mechanism for easily performing analysis of execution of a series of program instructions. PSOLUTION: The data processing system 1 has a processor core 2 which is programmable to act as one of a plurality of virtual machines each identified by a virtual machine identifier. Each virtual machine operates in one of a plurality of contexts each identified by a context identifier. Each context executes a series of program instructions. Each program instruction has one or more associated memory addresses. The data processing system has a diagnostic circuit 10 for performing diagnostic operations on the processor core. Diagnostic control circuit 12 is provided which triggers the diagnostic circuitry 10 to perform diagnostic operations is in response to at least one current value among the virtual machine identifier, the context identifier and one or more of associated memory addresses.
