Patent ID: 8316017

Claim:
A computer system module comprising: a sense circuit coupled to a first system resource, the sense circuit configured to: detect an inappropriate access to the computer system during a processing activity involving the first system resource, the inappropriate access including either an access of the first system resource involved in the processing activity or an access of at least one of any further system resources associated with the processing activity involving the first system resource, and upon detection of the inappropriate access activate a signal flag indicating the inappropriate access; a sample-and-hold circuit coupled to the sense circuit and configured to: receive the signal flag from the sense circuit; generate an inappropriate access signal based on the signal flag; and forward the inappropriate access signal to a gating logic circuit, the sample-and-hold circuit including a feedback latch loop that is configured to retain a record of the inappropriate access upon receiving the signal flag from the sense circuit, the record of the inappropriate access being maintained until a reset flag is received; and the gating logic circuit that is configured to respond to the inappropriate access signal by generating a trigger on an access line coupled to the first system resource such that the processing activity involving the first system resource is halted.
