Delay-insensitive asynchronous ALU for cryogenic temperature environments


This paper details the design and performance of a delay-insensitive asynchronous 8-bit ALU for an asynchronous 8051-compliant microcontroller intended for extreme environments. The ALU was designed using a quasi-delay-insensitive logic called NULL Convention Logic (NCL), in order to allow for reliable circuit operation over a wide temperature range and… (More)
