Synchronization of concurrent computation engines

Abstract:

Provided are systems and methods for synchronizing program code execution for a plurality of execution engines in an integrated circuit device. In some cases, the operation of one execution engine may be dependent on the operation of another execution engine. To accommodate this dependency, the instructions for the first execution engine can include a set-event instruction and the instructions for the second execution engine can include a wait-on-event instruction. The wait-on-event instruction can cause the second execution engine to wait for the first execution engine to reach the set-event instruction. In this way, the two execution engines can be synchronized around the data or resource dependency.
