There is no systematic design for shared resource access priority in platform side, and there is no interface provided byplatform that can be used by application to do bandwidth management optimization. Different application has different traffic model and different bandwidth management requirement, so we need to analyze application traffic model and give optimized bandwidth management scheme.

When more than one master request shared resource access at the same time, which one will be serviced firstly? It can be configured by some registers in Nyquist, the system masters in Nyquist includecore(core0,1,2,3), IDMA, EDMA, CDMA(packet DMA, 如FFTC,AIF2等协处理器均使用packet DMA来传输数据) andSRIO DIO, every shared resource can be configured with a access priority and maximum wait time for every system master.
