Abstract
A communication link protocol is provided for communicating between nodes of an interconnect system via a communication link. In one embodiment, the communication link protocol includes a direct memory access (DMA) command for writing a block of data from a local node to a remote node via the communication link; an administrative write command for writing data from a local node to registers in a remote node via the communication link for administrative purposes; a memory copy write command for writing a line of memory from a local node to a remote node via the communication link when any data is written into that line of memory; and a built in self test (BIST) command for testing the functionality of the communication link.
