Abstract: A math engine is provided capable of supporting large complex mathematical computations, such as modulo math computations involved in cryptography, while remaining easily reconfigurable, upgradeable and scalable. As new algorithms and specifications are desired to be solved, the math engine can be easily updated to accommodate the new requirements. These systems employ layers of cells, wherein individual cells are responsible for calculations. Thus, the complexity of the mathematical computation is broken down into cells which are easily added, removed, changed or substituted. The cells may be interchangeable and programmable, and provide flexibility and reconfigurability to the system at low or near-zero cost. When additional algorithms are desired, additional appropriate cells are simply added or changed.
