At Intel Developer Forum, numerous research projects were on display. One of the projects demonstrated a low voltage resilient processor that automatically adapts its power-performance point to achieve the best throughput at minimum energy. One of the recurring themes at this year’s IDF is energy efficiency. It is exciting to see so many projects that are taking proactive steps to be more environmentally conscious.The attached video demonstrates a low voltage resilient processor that automatically adapts its power-performance point to achieve the best throughput at minimum energy. The distributed sensors and error detectors on the die enable automatic reissue of instructions or automatic adaptation of the operating conditions to achieve error-free performance beyond typical dynamic guardbands set by voltage, temperature and aging over lifetime of the product. This is the first “processor” prototype in Intel’s MG/hi-K 45nm process technology that can run code and has the capability to adapt to changing environment conditions, respond to slow degradations over its lifetime, can detect and correct infrequent failures on the fly in hardware. It promises major gains in energy efficiency and performance under wide dynamic operating conditions depending on its unique usage scenario.
