Research of the Direct Memory Communication Method
At present, the speed of the communications on PCI is limited by PCI bus, the number of the computers memory slots and the memory capacity significantly increased, and the management of memory becomes advanced. So, in this paper, the Direct Memory Communication method, abbreviated as DMC, is forwarded. The NIC (the Network Interface Card) based on DMC is inserted into a memory slot, the data is written into the memory while its written into the NIC, and the user can accomplished the direct point-to-point communications between the computers through accessing memory. The communications speed isnt limited by PCI bus, and the copy between memory and NIC is omitted. The author also applied DMC into the high-speed fibre channel switch network, and has been studying the DMC-NIC based on the FB-DIMM DDR2. The experiments result shows that this NIC has the following advantages: a higher communications speed, a smaller communications delay and a simpler operation method.
