/Low Latency Reset Synchronizer Circuit
Abstract

A first latching circuit has a reset function controlled by a reset signal and configured to latch a logic state in response to a first edge of a clock signal to generate a first output signal. A second latching circuit has a reset function controlled by that reset signal and configured to latch a logic state in response to a second edge of that clock signal to generate a second output signal. The first and second edges are opposite edges. A combinatorial logic circuit logically combines the first and second output signals to generate a logic output signal. A third latching circuit has a reset function controlled by that reset signal and configured to latch the logic output signal in response to the second edge of that clock signal to generate a reset synchronization control signal.

What is claimed is:

A first latching circuit has a reset function controlled by a reset signal and configured to latch a logic state in response to a first edge of a clock signal to generate a first output signal. A second latching circuit has a reset function controlled by that reset signal and configured to latch a logic state in response to a second edge of that clock signal to generate a second output signal. The first and second edges are opposite edges. A combinatorial logic circuit logically combines the first and second output signals to generate a logic output signal. A third latching circuit has a reset function controlled by that reset signal and configured to latch the logic output signal in response to the second edge of that clock signal to generate a reset synchronization control signal.
