Stack-based trace message generation for debug and device thereof

摘要

During a debug mode of operation of a data processor it is determined whether a data access request is to a stack of the data processor. If not, a data trace message based on the data access request is generated for transmission to a debugger so long as an address being accessed by data access request meets a predefined address range criteria. Otherwise, if the data access request is to the stack of the data processor, a data trace message based on the data access request is prevented from being generated for transmission to the debugger regardless the predefined address range criteria.

1. A method comprising:
storing a first address range that is used to qualify whether data trace information is to be stored at a trace buffer; generating a first data access request by a data processor to access a first storage location; and in response to the first storage location belonging to a memory stack of the data processor, not storing data trace information of the first data access request at the trace buffer irrespective of the first address range, otherwise, in response to the first storage location not belonging to the memory stack of the data processor, storing data trace information of the first data access request at the trace buffer in response to determining the first storage location is within the first address range.
