Speed and Energy Optimised Quasi-Delay-Insensitive Block Carry Lookahead Adder
P. Balasubramanian, D. L. Maskell, N. E. Mastorakis
We present a new asynchronous quasi-delay-insensitive (QDI) block carry lookahead adder with redundancy carry (BCLARC) realized using delay-insensitive dual-rail data encoding and…
Majority and Minority Voted Redundancy for Safety-Critical Applications
P Balasubramanian, D L Maskell, N E Mastorakis
A new majority and minority voted redundancy (MMR) scheme is proposed that can provide the same degree of fault tolerance as N-modular redundancy (NMR) but with fewer function unit…
Power, Delay and Area Comparisons of Majority Voters relevant to TMR Architectures
P Balasubramanian, N E Mastorakis
N-modular redundancy (NMR) is commonly used to enhance the fault tolerance of a circuit/system, when subject to a fault-inducing environment such as in space or military systems, w…
Global versus Local Weak-Indication Self-Timed Function Blocks - A Comparative Analysis
P Balasubramanian, N E Mastorakis
This paper analyzes the merits and demerits of global weak-indication self-timed function blocks versus local weak-indication self-timed function blocks, implemented using a delay-…
ASIC-based Implementation of Synchronous Section-Carry Based Carry Lookahead Adders
P Balasubramanian, N E Mastorakis
The section-carry based carry lookahead adder (SCBCLA) topology was proposed as an improved high-speed alternative to the conventional carry lookahead adder (CCLA) topology in prev…
