Abstract: Examples herein describe compiling source code for a heterogeneous computing system that contains jump logic for executing multiple accelerator functions. The jump logic instructs the accelerator to execute different functions without the overhead of reconfiguring the accelerator by, e.g., providing a new configuration bitstream to the accelerator. At start up when a host program is first executed, the host configures the accelerator to perform the different functions. The methods or system calls in the host program corresponding to the different functions then use jump logic to pass function selection values to an accelerator program in the accelerator that inform the accelerator program which function it is being instructed to perform. This jump logic can be generated by an accelerator compiler and then inserted into the host program as a host compiler generates the executable (e.g., the compiled binary) for the host program.
