Abstract
A stream manager for managing the distribution of instructions to a plurality of processing devices includes a dispatcher module configured to: receive multiple instruction streams, wherein each instruction stream includes a plurality of requested computations for processing perception data from a perception data source; partition each instruction stream into a plurality of partitions based on type of device to perform a requested computation from the instruction stream; assign a release time and deadline to each partition, and dispatch partition computations to a plurality of scheduling queues to distribute processing of the partition computations amongst the plurality of processing devices. The plurality of scheduling queues include: a plurality of CPU schedulers, wherein each CPU scheduler is assigned to a specific CPU and a specific scheduling queue; and a plurality of accelerator schedulers, wherein each accelerator scheduler is assigned to a specific scheduling queue and a specific type of accelerator.
