The P2P Communication Model for a Local Memory based Multi-core Processor

Multi-core processor has become the mainstream processor nowadays. Data communication between different cores becomes a main problem especially when many cores need to get data from one core. Traditional Client/Server mode communication pattern tends to cause the server node to be the bottleneck and only uses the transfer path between the client and server nodes. A P2P communication model is proposed to solve this problem for a local memory based multi-core processor. It helps to alleviate the server core pressure and to form a multi-path transfer which makes full use of the bottom transfer network. Simulation results show that the proposed model provides a better performance than the traditional C/S mode communication which indicates that it is a promising communication model and can be used for other multi-core processors.
