基于FPGA的DSP访问DS12887时钟芯片的设计

Accessing DS12887 by DSP based on FPGA

为了实现DSP(如TMS320LF2407)对实时时钟芯片DS12887的访问,本文提出了用FPGA完成时序转换的方法,同时给出详细的操作过程。

The timing of real - time clock DS12887 is introduced at first. Since it is unsuitable for direct access by Digital Signal Processing （such as TMS320122407）, a sequence conversion method is put forward by using Field Programmable Gate Array （FPGA）, and the detailed process of operation is introduced in the paper.
