为了降低大负载地址总线的功耗,提出了一种新的低功耗自适应偏移量总线编码方法.该编码方法采用排序数列索引进行偏移地址总线的自适应重排,通过冗余线实现最佳排序数列至存储器地址接收端的传送,相对于传统的地址总线编码方法,具有更低的总线翻转频率.验证结果表明,采用自适应偏移量总线编码,地址总线的翻转频率降低了86.6%,功耗减少了69.2%,编码器本身的动态功耗和面积相当小,有效地实现了地址总线的低功耗工作. In order to reduce the power consumption of the heavy load address bus, a new low power consumption adaptive offset bus coding method is proposed, which uses the sorted sequence index to adaptively rearrange the offset address bus, Compared with the traditional method of address bus coding, the bus inversion frequency is lower than that of the traditional address bus coding method. The verification results show that using adaptive offset bus coding, the inversion frequency of the address bus is reduced by 86.6 %, The power consumption is reduced by 69.2%. The dynamic power consumption and the area of ​​the encoder itself are quite small, which effectively realizes the low power consumption of the address bus.
