and the increase of transmission data results in increasingly high requirement on transmission efficiency. However
there is a serious waste of USB bandwidth resources
due to the USB system software and characteristics of devices. A USB bulk transfer transaction scheduling method with SARSA learning algorithm for this problem
intelligently allocating the transactions in each frame based on current environment is designed. Simulation results show that this method significantly improves the utilization effectiveness of USB bandwidth and the throughput
compared to the method of the USB system
in the case of multiple bulk transfers.
