运动视觉处理SOC可测性设计与实现

Design and Implementation of DFT for a Moving Computer Vision SOC

在设计运动视觉处理SOC时 ,本文中采用了基于IP的结构 ,虽然有设计方法先进、可复用等优点 ,但也使得SOC复杂性增加 ,也加大了系统芯片内部的数据通路完整性、IP和处理器等的测试难度。本文采用了基于IEEEP1 5 0 0的测试框架结构以及BIST方法对此SOC以及其中的IP进行可测性设计的方法 ,有效地改善了整个SOC的测试性能 ,提高了SOC的可靠性。

A Computer Vision SOC was designed with IP-based structure, and its test for data integrality and IP & processor core became much difficult. We introduced a DFT method that based on the IEEE 1500 and BIST structure in the SOC and IPs. This method improved its test performance as well as the reliability of the SOC. Also, the result of simulation showed that it is a good method to solve this kind of problem.
