Abstract
A system for executing an accelerator call function includes a processor, a register context memory, an accelerator scheduler, multiple accelerator cores, and a stack memory. The processor executes a program task. The processor includes a register that stores task context information of the program task. The accelerator call function includes an accelerator operation. The processor forwards the accelerator operation to the accelerator scheduler. Concurrently, the processor stores the task context information in the register context memory. The accelerator scheduler identifies one of the accelerator cores and forwards the accelerator operation to the identified core. The identified core executes the accelerator operation, generates a return value, and stores the return value in the register context memory, which in turn provides the return value and the task context information to the processor.
