METHOD FOR REDUCING INTERRUPT LATENCY IN EMBEDDED SYSTEMS

摘要

The various embodiments of the present invention disclose a method for reducing interrupt latency in embedded systems. According to an embodiment of the present invention, the method for reducing interrupt latency in embedded systems, the method comprises steps of toggling, by a processor, from a supervisor (SVC) mode to an interrupt request (IRQ) mode on receiving an interrupt, identifying, by an interrupt service routine (ISR) stack, a Task Control Block (TCB) of a preempted task on receiving the interrupt, enabling, by the processor, the IRQ stack as a pseudo context page table, and storing the preempted task context information in the IRQ stack, wherein a complete register set is stored in IRQ stack as first activity before processing the received interrupt thereby enabling reduced interrupt latency.
