Abstract
The disclosed embodiments provide a synchronization circuit that supports multiple parallel reads and writes. This synchronization circuit includes multiple coupled data storage locations that synchronize data and control signals between two time domains and control logic that facilitates simultaneously accessing a variable number of such data storage locations in the same clock cycle. During operation, the synchronization circuit receives a request to simultaneously access (e.g., read and/or write) two or more synchronized data storage locations. In response to the request, the control logic in the synchronization circuit determines whether the present state of the synchronization circuit can accommodate the request, and if so, simultaneously accesses two or more synchronized data storage locations.
