With the development of the high-integrated chip technology,there are now a lots of function chips.For example,the PSD family, i.e.,under-line programmable interface system of WSI in USA.In this paper,the interface method of ADSP-2105 and PSD311 has been discussed in detail,the proposed controller based on the two-chips has been also explained about the characteristics and related problems,the design result to the two-chip is given at last.
