Abstract
The bandwidth and throughput rate are very important indexes for the performance parameters of mobile phone chip, which are the essential assessment carried on by the third-party for the mobile phone acceptance testing nowadays.However, drawback still exists in this kind of testing.The bandwidth and throughput rate of mobile phone cannot be presented fully and veritably by using these popular methods.This paper mainly discussed the difference of effects on testing the bandwidth and throughput rate of mobile phone by the way of manipulating the model of CPU, Cache and DDR from the aspect of operating hardware, and made a comparison with the most common used ARM system and CPU system.At last, a noval evaluation method of the bandwidth and throughput rate of mobile phone is proposed by this paper.关键词
