摘要

本文提出了一种用一些等效计数器代替寄存器的新方法,从而在不损失原始数据的情况下减少功耗和门数。如果任何一组频繁0或1至少有五个原始成员,这些计数器将计算寄存器中连续0或1的数量,并保存它们而不是原始序列。当输入数据只有1和0时,这种方法是游程编码方法的一种扩展形式,可用于压缩δ - σ信号,增加有效信道带宽,例如在USB通信中。文中给出了两个例子来说明这种方法的有效性。

Power dissipation and gate number reduction of a utilized register, replaced by equivalent counters
This paper proposes a new method to replace registers with some equivalent counters and consequently to reduce power dissipation and gate numbers without any loss in the original data. If any set of frequent zeros or ones have at least five original members, these counters calculate the number of consecutive zeros or ones in the register and save them instead of the original sequence. This method is an extended form of Run-Length encoding method when input data is only one and zero and can be used to compress delta-sigma signals and to increase effective channel bandwidth, for instance in USB communication. Two examples arc given to illustrate the efficiency of this approach.
