  • Processor circuit comprising a first processor, a memory and a peripheral circuit, and system comprising the processor circuit and a second processor
    Patent number: 5574929
    Abstract: Personal computers, a first processor and a second processor belonging to a processor circuit such as a PC card, communicate with one another via a quasi dual-port RAM. The first processor and the second processor alternately read data out of the RAM and write other data into the RAM. Furthermore, the second processor communicates directly with an associated peripheral device. By offering the possibility of, in a first mode, communication between the first processor and the RAM, and communication among the second processor, the peripheral device and the RAM and, in a second mode, communication between the first processor and the peripheral device without using the RAM and without the intervention of the second processor, the PC card becomes sufficient for test purposes and permits backup possibilities. By storing a synchronization protocol into the first processor and into the second processor, the first processor and the second processor can be easily synchronized with each other.
