主从式片上总线系统交易级的实现

Implementation of Bus-on-chip System with Master-slave Pattern at Transaction Level

在总线的主设备上增设了实时操作系统的任务优先级分配机制,基于蒙特卡罗选择实现总线仲裁器的仲裁策略,建立不同类型的从设备存储器模型。运用SystemC在交易级实现整个总线系统模型,并对该模型进行仿真。实验结果证实了仲裁算法的有效性。

The mechanism of task priorities assignment in Real Time Operating System（RTOS） for master devices is added, and the arbitrate policy of arbiter based on Monte Carlo methods is implemented. Moreover, various memory models for slave devices are also set up. The whole model of bus system is completed at transaction level by using SystemC. Simulation results illustrate this arbitrate algorithm is effective.
