摘要：An interrupt controlled prefetching and caching technique includes transferring peripheral data from a peripheral to a peripheral cache via direct memory access in
respon to receiving an interrupt request from the peripheral. The technique includes executing an interrupt rvice routine prologue in respon to completion of transferring of peripheral data. The technique may include providing a ba address and a transfer trigger to initiate the transferring of the peripheral data. The technique may include executing a peripheral interrupt rvice routine after executing the interrupt rvice routine prologue. The technique may include executing an interrupt rvice routine epilogue after executing the peripheral interrupt rvice routine, the interrupt rvice routine epilogue including retting an interrupt status flag associated with the interrupt request. Executing the interrupt rvice 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.
