Why ARM processors are the best choice for embedded low-power applications?

摘要

ARM®''s success to date has been largely due to its remarkable performance/power (MIPS/Watt) rating, and this will likely continue to be its most critical benchmark for future applications. This paper considers the way in which attention to interdependent detail in intelligent voltage management, cache controller design, conditionally executable instructions, and interrupt control hardware contribute to the ARM architecture''s high performance and low power operation.
