Abstract
A multiprocessor system includes first and second processing units. Each of these processing units includes at least a processor and preferably also a cache memory, a cache memory controller and a numerical coprocessor. Each processing unit is reset in response to a system reset signal but only selected portions of the processing units are reset in response to a partial-reset signal. The system can also include a number other components such as video circuitry, a hard disk drive, bus interface circuitry, a speaker, a keyboard controller and a keyboard.
