Interrupt Controlled Prefetching and Caching Mechanism for Enhanced Processor Throughput

An interrupt controlled prefetching and caching technique includes transferring peripheral data from a peripheral to a peripheral cache via direct memory access in response to receiving an interrupt request from the peripheral. The technique includes executing an interrupt service routine prologue in response to completion of transferring of peripheral data. The technique may include providing a base address and a transfer trigger to initiate the transferring of the peripheral data. The technique may include executing a peripheral interrupt service routine after executing the interrupt service routine prologue. The technique may include executing an interrupt service routine epilogue after executing the peripheral interrupt service routine, the interrupt service routine epilogue including resetting an interrupt status flag associated with the interrupt request. Executing the interrupt service routine may include executing instructions using the peripheral data at a rate at least an order of magnitude faster than an access time of the peripheral.
