摘要
地址总线的功耗是整个 CPU卡电路系统功耗的重要来源。降低地址总线上的翻转率可以有效降低整个系统的功耗。文章在分析 CMOS电路功耗和几种总线编码的基础上 ,提出了一种改进的 T0 - BI编码 ,并将此种编码应用于 CPU卡用芯片的设计。结果表明 ,采用此种编码可以有效地降低 CPU卡电路的功耗。
The power dissipated by the address bus is the most important power dissipation source of the CPU card Reducing the toggle rate on the address bus can cut down the power of the whole system effectively Based on the analysis of the power dissipation in COMS circuits and the analysis of the known address coding,an advanced T0 BI coding is proposed in the paper,which has been applied to the design of a CPU card It is demonstrated that the system power dissipation of the CPU card has been reduced effectively
