摘要
电路软核因费用较低和使用灵活而得到越来越多的应用,但目前的大部分加密方式不适合软核。介绍了一种适用于软IP核设计开始时采用的数字水印嵌入方法,并以4-2编码器为例说明数字水印嵌入软核的方法,并对水印化后电路的性能和开销进行了分析和实验。
Due to the low cost and flexibility, soft IP core is becoming more and more popular, but most intelligence property protection ways are not suitable for such kind of IP. A watermarking designed soft IP cores was introduced, and 4-2 encoder design was given as an example both embedded and reading processes are quite simple and cost low.
