Low Power Design – where next for Power-Gating?
January 18, 2012 // David Flynn, ARM // 0 commentsDownload White Paper 835Ko
On-chip power gating is well understood and supported by multi-voltage EDA tools and Unified and Common Power Formats (UPF and CPF), but has limitations. This paper describes new techniques, developed and evaluated in silicon in R&D at ARM, that enhance power gating and address state retention with minimal area and performance impact. Appropriate for Cortex-A class to Cortex-M class SOC designs.
