High temperatures have dramatic negative effects on interconnect performance. In a bus, whenever the state transitions from “0” to “1”, or “0” to “1”, joule heating causes the temperature to rise. A low-power error-correcting cooling (LPECC) code, introduced in Chee et al. (IEEE Trans Inf Theory 64:3062–3085, 2018), is a coding scheme which can be used to control the peak temperature, the average power consumption of on-chip buses and error-correction for the transmitted information, simultaneously. In this paper, we show upper bounds and some lower bounds of LPECC codes by some combinatorial configurations, and also present several families of optimal LPECC codes.

高温会对互连性能产生巨大的负面影响。在总线中，每当状态从“0”转变为“1”，或从“0”转变为“1”时，焦耳热就会导致温度升高。 Chee 等人提出了一种低功耗纠错冷却 (LPECC) 代码。 （IEEE Trans Inf Theory 64:3062–3085, 2018）是一种编码方案，可用于同时控制峰值温度、片上总线的平均功耗以及传输信息的纠错。在本文中，我们通过一些组合配置展示了 LPECC 码的上限和一些下限，并且还提出了几个最佳 LPECC 码族。
