Genetic algorithm based state assignment for power and area optimisation. (2002)
Journal Article
Xia, Y., & Almaini, A. E. A. (2002). Genetic algorithm based state assignment for power and area optimisation. IEE proceedings. Computers and digital techniques, 149, 128-133. https://doi.org/10.1049/ip-cdt%3A20020431

The use of assignment to minimise power dissipation and area for finite-state machines is computationally difficult. Most published results show that the reduction of switching activity often trades with area penalty. Two cost functions are introduce...

Decomposition techniques are utilised for mixed polarity Reed-Muller minimisation, which lead to Reed-Muller programmable logic array implementations for Boolean functions. The proposed algorithm produces a simplified mixed polarity Reed-Muller forma... Read More about Optimisation of Reed-Muller PLA implementations..

Differential CMOS edge-triggered flip-flop with clock gating. (2002)
Journal Article

Modulo correlativity and its application in a multiple valued logic system (1998)
Journal Article
Wang, L. Y., Chen, X., & Almaini, A. E. A. (1998). Modulo correlativity and its application in a multiple valued logic system. International Journal of Electronics, 85(5), 561-570. https://doi.org/10.1080/002072198133851

Several new concepts such as pseudoprime and correlativity, are presented. Then modulo subtraction and modulo division, which are very useful in computing the canonical expansion, are proposed in a multiple valued modulo algebra system with either a...

It has been claimed for some time that the Reed-Muller technique can yield a simpler arithmetic circuit if it is employed in the design procedure. In fact, no practical application in this field can be found in the open literature. This paper attempt... Read More about One-bit adder design based on Reed-Muller expansions.
