Abstract
A processor couples to a system bus and includes a high performance microprocessor which tightly couples to a local memory. The processor is organized at the interface level into a plurality of interface sections which include a corresponding number of state machines for enabling the simultaneous processing of a plurality of different types of transactions or requests under all conditions. One interface section is organized to include the system visible registers which are accessible for reading and writing by I/O commands received from the system bus. Another section processes memory commands received from the system bus while a further section processes read/write and I/O commands issued to the system bus by the processor.
