PROCESSOR I/O AND INTERRUPT FILTERS |
摘要 |
<p>PROCESSOR I/O AND INTERRUPT FILTERS A co-processor is connectable to a main system data bus to run software unknown to the main processor. The main processor can concurrently run other software and maintains priority over shared I/O facilities by providing trapping logic incorporated in a random access memory and dynamically loadable by the master processor which contains data related to the current useability by the co-processor of a shared I/O device. Additional logic is associated with the co-processor to manage interrupts between the co-processor and the system bus.</p> |
