Further power and energy reductions via technology and voltage scaling have become extremely difficult due to leakage and variability issues. In this paper, we present a robust and energy-efficient computation architecture exploiting an asynchronous timing strategy to dynamically minimize leakage and to self-adapt to process variations and different operating conditions. Based on a logic topology...
Unlike static CMOS circuits, the standby energy in sense amplifier-based pass transistor logic (SAPTL) circuits can be decoupled from its performance, allowing separate optimization strategies for leakage and speed. In this paper, a 64-byte parallel cyclic-redundancy check (CRC) generator is designed and implemented using asynchronous 90nm SAPTL circuits, with a simulated minimum energy point that...
This paper presents the design and implementation of a low energy asynchronous logic architecture using sense amplifier-based pass transistor logic (SAPTL). The SAPTL structure can realize very low energy computation by using low leakage pass transistors and low supply voltage. The introduction of asynchronous operation in SAPTL further improves energy-delay performance and reliability without increasing...
