Cost Efficient Design Approach for Reversible Programmable Logic Arrays
Md. RiazurRahman · 2016
Reversible programmable logicarrays (PLA) are at the heart of designing of efficient low power computers. This paper presents anefficient approach to design Reversible PLAs that maximizes the usability of garbage outputs and also reduces the number of ancilla inputs generated. The designfor proposed essentialcomponents and the architecture of reversible grid network for designing AND and EX-OR planes are also presented. Several algorithms have been proposed and presented to describe the programming interfaces in context of Reversible PLAs construction. Lastly, recent result on the trade-off between cost factors of standard benchmarkcircuits shows that the proposed design clearly outperforms the existing ones in terms various cost factors.
