Abstract
The general bus architecture consists of masters, slaves, arbiter, decoder and so on in shared bus. Specially, as several masters do not concurrently receive the right of bus usage, the arbiter plays an important role in arbitrating between shared bus and masters. Fixed priority, round-robin, TDMA and Lottery methods are developed in general arbitration policies, which lead the efficiency of bus usage in shared bus. On the other hand, the bus architecture can be modified to maximize the system performance. In the paper, we propose the flying master bus architecture that supports the parallel bus communication and analyze its merits and demerits following various arbitration policies that are mentioned above, compared with normal shared bus. From the results of performance verification using TLM(Transaction Level Model), we find that more than 40% of the data communication performance improves, regardless of arbitration policies. As the flying master bus architecture advances its studies and applies various SoCs, it becomes the leading candidate of the high performance bus architecture.
