本文介绍了上下文无关编码的概念,使用基于频率的映射方案,以减少片外互连功耗。处理器-SDRAM片外接口的最先进的上下文相关双端代码要求发射器和接收器(存储器控制器和SDRAM)使用当前和先前传输的值进行协作,以编码和解码数据。相反,存储器控制器可以使用上下文无关的代码来编码存储在SDRAM中的数据,并且随后在检索该数据时对其进行解码,从而允许使用商用存储器。在本文中,一个单端,上下文无关的代码是通过分配有限重量的代码,使用基于频率的映射技术实现的。实验结果表明,这样的代码可以减少一个未编码的芯片外互连的功耗平均为30%,小于0.1%的性能下降。
This paper introduces the concept of context-independent coding using frequency-based mapping schemes in order to reduce off-chip interconnect power consumption. State-of-the-art context-dependent, double-ended codes for processor-SDRAM off-chip interfaces require the transmitter and receiver (memory controller and SDRAM) to collaborate using current and previously transmitted values to encode and decode data. In contrast, the memory controller can use a context-independent code to encode data stored in SDRAM and subsequently decode that data when it is retrieved, allowing the use of commodity memories. In this paper, a single-ended, context-independent code is realized by assigning limited-weight codes using a frequency-based mapping technique. Experimental results show that such a code can reduce the power consumption of an uncoded off-chip interconnect by an average of 30% with less than a 0.1% degradation in performance.
