Abstract
A system fabricated on a single integrated circuit chip includes a microprocessor operating from a high speed bus and a peripheral bus operating in conjunction with high speed bus through a bus bridge . A first set of processing resources operate from high speed bus and includes an external memory interface , a direct memory access engine for controlling the exchange of information through memory interface , and a boot memory for storing boot code. A second set of processing resources operate from peripheral bus and includes an interrupt controller for issuing interrupt requests to microprocessor , a set of programmable timers for generating timed interrupt signals, and a phase locked loop for generating timing signals.
