Interrupt reduction
摘要:
An interrupt reducing device driver module reduces the rate at which interrupts from a peripheral burden a processor. The interrupt reducing device driver determines when data is associated with the interrupt. When data is present, such as when indicated by an interrupt status register, further interrupts are masked and a buffer associated with the peripheral is read-out. This read-out continues while data is present in the buffer. Once no further data is present, the data interrupts are unmasked. Reduction in the rate of interrupts prevents resource starvation and improves overall system response. Additionally, the processor and associated components are able to enter and remain in low power modes, improving battery life.
