Abstract
Systems, apparatuses, and methods for error detection and recovery when streaming data are described. A system includes one or more companion direct memory access (DMA) subsystems for transferring data. When an error is detected for a component of the companion DMA subsystem(s), the operations performed by the other components need to gracefully adapt to this error so that operations face only a minimal disruption. For example, while one or more consumers are still consuming a first frame, a companion router receives an indication of an error for a second frame, causing the companion router to send a router frame abort message to a route manager. In response, the route manager waits until the consumer(s) are consuming the second frame before sending them a frame abort message. The consumer(s) flush their pipeline and transition to an idle state waiting for a third frame after receiving the frame abort message.
