METHOD FOR REDUCING PROCESSOR INTERRUPT LOAD |
摘要 |
A method for reducing interrupt load in a multi-processor system (10) is disclosed, whereby two central processors (12, 14) executing a real-time operating system can communicate with each other using a shared memory (16). A start pointer (18) and end pointer (20) are implemented preferably in logic (150). By detecting a difference in the logic values for the two pointers (18, 20), the receiving CPU (14) will receive interrupts only when new data from the sending CPU (12) has arrived in the shared memory (16) and the shared memory was empty. Consequently, the operating system will not be disturbed with unnecessary interruptions, and the interrupt load will thus be low.
