    摘要: A method and apparatus for serial communication with a co-processor. In one embodiment, a microprocessor is provided with a CPU core, set of serial interface registers, a serial interface unit, to provide serial communication between a co-processor and the microprocessor. The set of serial interface registers is part of a register file of the CPU core and interrupts are exchanged between the CPU core and the co-processor to allow for reading and writing of data placed in the serial registers of the register file.

    摘要: An apparatus and method for controlling the stopping of the clock signal utilized by the processing unit of a computer system comprises the use of a novel external pin which can be enabled to initiate a sequence of events that results in the halting of the internal clock signal. The invention includes a microcode engine that responds to the assertion of the external pin by executing a sequence of steps which stops the current instruction on an instruction boundary. A logic circuit then generates a signal that masks the clock signal produced by the system's phase-locked loop. An interrupt mechanism is also utilized to prioritize the occurrence of the external signal among other system interrupts. The interrupt mechanism insures that the processor never has its clock stopped in the middle of a bus cycle.

    摘要: A microprocessor for use in a computer system which pipelines addresses for both burst and non-burst mode data transfers. By pipelining addresses, the microprocessor is able to increase the throughput of data transfers in the system. In the present invention, bits are used which may be programmed to disable and enable the address pipelining for the non-burst mode and burst mode transfers.
