A novel network communication model based on Cell, which is a multi-core processor system, is presentment. And the I/O data transmission performance of the novel system will be showed in the paper too. In order to meet the high computation capacity request, the multicore platform has been adopted in the software radio system. But the research result presents that the data I/O transmission becomes the bottleneck for the software radio system. To resolve the problem, the paper redesign the network model based on Cell system, moving the protocol stack and net device driver components to SPU from PPU. The novel model cannot only release the PPU resource, but also has efficient I/O transmission performance.
