US Patent 10896140 Controlling operation of multiple computational engines

The present disclosure relates to a computer-implemented method for controlling operation of multiple computational engines of a physical computing device. The computer-implemented method includes providing a multiplexer module in the device, the multiplexer module including a first and second memory region. The multiplexer module may receive from a first driver at the multiplexer module a data processing request to be processed by a first set of one or more computational engines of the computational engines. Subsequent to receiving the data processing request, the multiplexer module may assign a request sub-region of the first region and a response sub-region of the second region to the first driver. Data indicative of the request sub-region and the response sub-region may be submitted to the first driver. Results of processing the request may be received at the response sub-region.
