This paper presents a practicable model for parallel processes in multi processor environment exploiting the semaphore mechanism. The model realizes the concurrent operations of multi processor, schedules the critical resources properly and the system performance is promoted. The analysis of the efficiency of the model is presented as well. The model is applied to the firmware design of CD ROM driver with high speed and the efficiency of the new system is superior to the old one′s.
