Abstract

A microprocessor having two on-board clock generators. The faster clock generator controls the microprocessor during normal, synchronous mode. The slower clock generator controls the microprocessor when the bus must be accessed, or during "snoop" mode which is invoked when another entry signals intent to use the bus.
