ABSTRACT:
An eventpoint chaining apparatus for generalized event detection and action specification in a processing environment is described. In one aspect, the eventpoint chaining apparatus includes a first processor which has a programmable eventpoint module with an input trigger (InTrig) input. The first processing element detects an occurrence of a first processor event (p-event) and produces an OutTrigger (OT) signal. The eventpoint chaining apparatus also includes a second processor which has a programmable eventpoint module with an input trigger (InTrig) input which receives the OT signal from the first processing element. The second processing element detects an occurrence of a second p-event and produces, in response to the OT signal received from the first processing element and the detection of a second p-event, an eventpoint (EP) interrupt signal. The eventpoint chaining apparatus also includes a sequence processor interrupt control unit for receiving the EP interrupt signals indicating the occurrence of both the first and second p-events and causing a p-action in response to the occurrence of both the first and second p-events.
