[问：hjb85]	如果DSP需要考虑外扩RAM，而且频率尽可能高，除了采用DMA还可以用什么方式
[答：Eyal]	For applications with high bandwidth of data, such as high end audio, the answer is yes, becasue otherwise the DSP will need to wait for the data, and thus it will not utilize its high performance capabilities. It can run without DMA, but, however in that case the DSP will need to do the actuall data copying from external memory, thus it will do simple data copying instead of complex DSP tasks, thus wasting its capabilities as a strong DSP.
