1. A method of processor communication in a multi-processor system containing a plurality of processors including at least first and second processors, the method comprising: providing each of the first and second processors with a respective internal processor communication register (PCR) that provides each of the first and second processors continuous access to the information stored within its respective PCR; the first processor retrieving information from one or more sectors of its respective internal PCR, wherein one of the sectors is allocated for storing by only said second processor; the second processor transmitting information on a dedicated interconnect connecting the PCR of the first processor and the second processor; each of the plurality of processors accessing data storage via a system interconnect separate from the dedicated interconnect; and the first processor storing the information transmitted by the second processor over the dedicated interconnect into the sector in the PCR allocated to the second processor.
