    1. cic filter contains integrators and differentiators. And the data in
    integrators have got to overflow. But it seems that setting a MSB for the
    integrators in every stages, and you could not care about the data
    overflow. But when i use the module function as the MSB in every
    integrators and simulate the system with Matlab, the result is strange and
    not the one that i want to get.
    2. Matlab 7 contains cic filters model. But each time i use this model,
    error message will come out and tell me that "Sample-based inputs are not
    currently supported in 'Maintain frame rate' mode for CIC decimation
