Switched Fabric CAN Optimization

Although the canbus limits, it stills used in all modern automobiles. Several researches focused on enhancing its reliability and data transfer speed. A combining between switching fabric technology and canprotocol produced an impressive results. By reflecting on the major performance boost especially on throughput, latency delay and loss probability we can touch the switching fabric contribution. In this paper we will present a new switched fabric can based on broadcast pattern. This latter solution is always a mixture between canprotocol and switched fabric technology where we played on the internal architecture of our previous model. By looking for a fast and reliable hardware solution, we replaced the crossbar pattern by broadcasting one. In fact, this latter is the most suitable pattern for the canprotocol by nature. The second major modification touches scheduler site. In order to obtain an optimized circuit frequency, we used just one scheduler that induce to reduce the integrated circuit area cost. As a result, the latency delay, the loss probability, the throughput, power consumption and clock threshold results show notable enhancing. In this paper, we modeled, implemented and evaluated a broadcasting switched fabric can. The implementation results was obtained by simulated the vhdl design under modelsim tool.
