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.

說明書

FIG. 5 is a block diagram illustrating an example of an integrated circuit device that includes global checkpoint registers and multiple execution engines that can have data inter-dependencies;

FIG. 6 is a sequence diagram illustrating an example of using checkpoints to synchronize execution engines in a local checkpoint register implementation;

FIG. 7 is a block diagram illustrating an example of an integrated circuit device that includes local checkpoint registers and multiple execution engines that can have data inter-dependencies;

FIG. 8 is a flowchart illustrating an example computer-implemented method for generating program code;

FIG. 9 includes a block diagram that illustrates an example of an acceleration engine; and

FIG. 10 includes a block diagram that illustrates an example of a host system.

DETAILED DESCRIPTION

The operations of an integrated circuit device such as a processor can be directed by instructions, which can be generated for the integrated circuit device by a compiler. A compiler is a software program that transforms programs written in human-readable programming language into machine language that can be understood by the integrated circuit device. The output of a compiler can be referred to as object code, program code, or program instructions, among other examples.
