Abstract
A circuit for detecting asynchronous events includes a first event detection latch; and a second event detection latch coupled to the first event detection latch, wherein the first event detection latch is ready to detect an event when the second event detection latch is being reset and wherein the second event detection latch is ready to detect a next event when the first event detection latch is being reset.
Claims20
A circuit for detecting asynchronous events comprising:
- a first event detection latch;
- and
- a second event detection latch coupled to the first event detection latch, wherein the first event detection latch is ready to detect an event when the second event detection latch is being reset and wherein the second event detection latch is ready to detect a next event when the first event detection latch is being reset.
A method for detecting asynchronous events, the method comprising:
- detecting a first event by a first event detection circuit;
- resetting the first event detection circuit after the first event is detected;
- detecting a second event by a second event detection circuit;
- and
- resetting the second event detection circuit after the second event is detected, wherein the first event detection circuit is ready to detect an event when the second event detection circuit is being reset and wherein the second event detection circuit is ready to detect a next event when the first event detection circuit is being reset.
2 more elements
A programmable circuit for detecting event signals comprising:
- a first programmable event detection circuit for detecting one of the group consisting a rising edge event, a falling edge event, a high level event, and a low level event;
- and
- a second programmable event detection circuit coupled to the first programmable event detection latch for detecting one of the group consisting a rising edge event, a falling edge event, a high level event, and a low level event, wherein the first and second programmable event detection circuits operate in a ping-pong manner for detecting events.
