降低总线功耗已成为低功耗片上系统（SoC）设计的关键问题之一。在本文中，我们提出了基于自适应码本方法的总线数据编码方案，该方案减少了总线线路的耦合信号转换以及自身信号转换。实验结果表明，所提出的编码方案在 16 位总线中将与功耗相关的有效信号转换减少了 25-50%，这表明所提出的方案适用于未来 SoC 设计中的 IP。
Reducing bus power dissipation has become one of key issues for low power System on a Chip (SoC) design. In this paper we have proposed bus data encoding schemes, which reduce coupling signal transitions of bus lines along with self signal transitions, based on adaptive code-book method. Experimental results show that proposed encoding schemes reduce effective signal transitions related to power dissipation as much as 25-50% in a 16-bit bus, which indicate the proposed scheme is suitable for IPs in future SoC designs.
