摘要

Integrated circuit devices and methods for synchronizing execution of program code for multiple concurrently operating execution engines of the integrated circuit devices are provided. In some cases, one execution engine of an integrated circuit device may be dependent on the operation of another execution engine of the integrated circuit device. To synchronize the execution engines around the dependency, a first execution engine may execute an instruction to set a value in a register while a second execution engine may execute an instruction to wait for a condition associated with the register value.

In various examples, local checkpoint registers can be used to synchronize the operations of two or more execution engines of the integrated circuit device. The accelerator engine 502 may include one checkpoint register associated with each execution engine in the accelerator engine 502. Each execution engine may wait on a condition associated with a value (i.e., a checkpoint) in its associated local checkpoint register. In the local register implementation, remote engines or the host processor may remotely set values in the checkpoint register of another execution engine but may not wait on the remotely set checkpoint values. The local checkpoint registers may be included in the hardware of the associated execution engines.

While FIG. 5 illustrates one example of an integrated circuit device that includes global checkpoint registers and multiple execution engines, other examples are possible. One of ordinary skill in the art would recognize many variations, modifications, and alternatives.
