Abstract:
1. A method for indicating warnings for a processing unit within a system, comprising: receiving an error event signal indicating that a programming error has been detected by the processing unit; capturing error state information of the processing unit in an error status register, wherein the capturing is triggered by the error event signal; updating an error bit to be asserted in the error status register that indicates an error event has occurred, wherein the error bit remains asserted until a reset signal is received; transmitting an error event signal to a monitoring unit to update an exception bit in an exception register included in the monitoring unit to indicate a hardware warning that the error event has been detected by the processing unit; receiving a second error event signal indicating that a second programming error has been detected by the processing unit while the error bit remains asserted; and transmitting a second error event signal to the monitoring unit while the error bit remains asserted.
