Abstract:
A system and method is provided for improved interrupt handling via a micro interrupt handler. Upon an interrupt signal being sent to a processor running a task, a first part of the running task is stored to system memory via direct memory access. A micro interrupt handler is read from the system memory to begin handling the interrupt signal. A second part of the running task is stored to system memory via direct memory access. The micro interrupt handler is executed and read and the previous running task is read from direct memory access and restored. Long lag times for interrupt processing and inefficiencies in processor queues are avoided.
