Methods and apparatus to emulate graphics processing unit instructions

An apparatus comprising:

• an interface;
• instructions in the apparatus;
• a first logic circuit to execute the instructions to cause the first logic circuit to:
• execute an instrumented kernel, the instrumented kernel including an emulation sequence for execution by the first logic circuit, the instrumented kernel generated based on an original kernel created for execution at a second logic circuit different from the first logic circuit;
• save, in response to determination that the emulation sequence is to be executed, source data to a shared memory;
• set an emulation request flag to indicate, to processor circuitry separate from the first logic circuit, that offloaded execution of the emulation sequence is to be executed;
• monitor the emulation request flag to determine whether the offloaded execution of the emulation sequence is complete;
• and
• access resulting data from the shared memory.
