A Complete Boolean Algebra Framework for Asymmetric Logic Functions in Emerging Computing Devices

Konsep Inti

A comprehensive algebraic framework tailored to asymmetric logic functions, such as inverted-input AND (IAND) and implication, to enable efficient synthesis and minimization of logic circuits for emerging computing technologies.

Abstrak

This paper presents a complete Boolean algebraic framework specifically designed for asymmetric logic functions, which are prevalent in emerging computing devices like memristors and spintronic devices. The framework introduces fundamental identities, theorems, and canonical normal forms that lay the groundwork for efficient synthesis and minimization of such logic circuits without relying on conventional Boolean algebra.

The key highlights are:

1. Algebraic identities and laws for IAND and IMPLY operations, including interaction with high/low logic, idempotency, commutation, associativity, distributivity, and De Morgan's law.
2. Canonical normal forms for asymmetric logic, including Sum of IANDs (SOI), NAND of Implications (NOI), IAND of Sums (IOS), and IMPLY of NANDs (ION).
3. Establishment of a logical relationship between IAND and IMPLY operations, showing that they are "De Morgan duals" of each other.
4. Demonstration of how this algebraic framework can enable significant computational advantages, as exemplified by a 28% reduction in computational steps for a memristive full adder circuit compared to previous manual optimization approaches.

The proposed algebraic framework lays the foundation for much greater future improvements in logic design automation for emerging computing technologies that leverage asymmetric logic functions.

How can this algebraic framework be extended to handle more complex Boolean expressions involving a larger number of asymmetric logic operations

To extend this algebraic framework to handle more complex Boolean expressions with a larger number of asymmetric logic operations, we can introduce rules for associativity and distributivity that apply to multiple operands. By defining how these operations interact with each other in a systematic manner, we can create a structured approach to simplify and manipulate expressions involving multiple asymmetric logic functions. Additionally, developing canonical forms for expressions with multiple asymmetric logic operations can help standardize the representation of complex Boolean functions, making them easier to analyze and optimize.
