Benefits of technology
The present invention is about a new type of processor that can perform complex mathematical functions more efficiently and with greater accuracy. The processor has a unique design that combines a memory array and an arithmetic logic circuit, allowing for faster and more effective processing. The processor can also be used to simulate complex systems and models, providing a more realistic representation of the underlying data. Overall, the invention provides a more powerful and efficient tool for scientific computation.
Problems solved by technology
However, logic circuits are not suitable for non-arithmetic functions, whose operations are more than the arithmetic operations performable by the conventional logic circuits.
Non-arithmetic functions are computationally hard and their hardware implementation has been a major challenge.
The 2-D integration severely limits computational density and computational complexity.
This has an adverse effect on parallel computation.
Apparently, the software-implemented functions (e.g. mathematical functions, mathematical models) run much slower and less efficient than the hardware-implemented functions (i.e. built-in functions), and extra software-decomposition steps (e.g. for mathematical models) would make these performance gaps even more pronounced.
Typical mathematical models are nonlinear and cannot be represented by a combination of these arithmetic operations.
This large amount of computation makes simulation extremely slow and inefficient.

A processor comprises an array of computing elements, with each computing element comprising an arithmetic logic circuit (ALC) and at least one three-dimensional memory (3D-M) array. The 3D-M array stores at least a portion of a look-up table (LUT) for a non-arithmetic function, while the ALC performs arithmetic operations on the LUT data.
