A method to decompose multiple-output logic functions
This paper shows a method to decompose a given multipleoutput circuit into two circuits with intermediate outputs. We use a BDD for characteristic function (BDD for CF) to represe...

Simultaneity Matrix for Solving Hierarchically Decomposable Functions
The simultaneity matrix is an × matrix of numbers. It is constructed according to a set of -bit solutions. The matrix element mij is the degree of linkage between bit positions i ...

A fast method to derive minimum SOPs for decomposable functions
- This paper shows that divide-and-conquer derives a minimum sum-of-products expression (MSOP) of functions that have an AND bi-decomposition when at least one of the subfunctions ...

On decomposing Boolean functions via extended cofactoring
—We investigate restructuring techniques based on decomposition/factorization, with the objective to move critical signals toward the output while minimizing area. A specific ap...

Decomposing the load-store queue by function for power reduction and scalability
Because they are based on large content-addressable memories, load-store queues (LSQ) present implementation challenges in superscalar processors, especially as issue width and nu...
