Data processing system with debug control

摘要

A data processing system includes a processor configured to execute processor instructions and a memory. The memory has a data array and a checkbit array wherein each entry of the checkbit array includes a plurality of checkbits and corresponds to a storage location of the data array. The system includes error detection/correction logic configured to, during normal operation, detect an error in data access from a storage location of the data array using the plurality of checkbits in the entry corresponding to the storage location. The system further includes debug logic configured to, during debug mode, use a portion of the plurality of the checkbits in the entry corresponding to the storage location to generate a breakpoint/watchpoint request for the processor.

1. A data processing system, comprising:
a processor configured to execute processor instructions; a memory coupled to the processor, the memory having a data array and a checkbit array, wherein each entry in the checkbit array includes a plurality of checkbits and corresponds to a storage location of the data array; error detection/correction logic configured to, during normal operation, detect an error in data accessed from a storage location of the data array using the plurality of checkbits in the entry corresponding to the storage location; and debug logic configured to, during debug mode, use a portion of the plurality of the checkbits in the entry corresponding to the storage location to generate a breakpoint/watchpoint request for the processor.
