A real-time and bandwidth guaranteed arbitration algorithm for SoC bus communication

– In shared SoC bus systems, arbiters are usually adopted to solve bus contentions with various kinds of arbitration algorithms. We propose an arbitration algorithm, RT_lottery, which is designed to meet both hard real-time and bandwidth requirements. For fast evaluation and exploration, gh abstract-level models in our system simulation environment to generate parameters for our configurable arbiter. The experimental results show that RT_lottery can meet all hard real-time requirements and perform very well in bandwidth allocation. The results also show that RT_lottery outperforms several commonly-used arbitration algorithms today.
