Power is a limiting constraint in spacecraft design. This paper' describes a Reed Solomon encoder designed for NASA using a triple metal, 0.35pm, ultra-low-power (500mV) CMOS process. Comparisons with a 3.3V version show a 29.6 to 1 reduction in power to 14.3 mW at 60 MHz. Hardness against space radiation effects was achieved through circuit and layout techniques.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
