Abstract
A communication system comprises an input-output processor IOP ( ) coupled to a plurality of network devices ( ) and a protocol processor PP ( ), both processors being coupled to a common memory ( ). Memory access control means ( ) resolves competition between the processors for memory access. Normally, if one of the two processors is accessing the memory, the memory control unit ( ) allows that access to be completed before allowing the other processor to access the memory. But if data loss in a network device is imminent, the IOP, is granted a higher priority memory access, the memory access controller aborts (interrupts) any memory access by the PP, allowing the IOP to access the memory immediately.
