Processor comprising three-dimensional memory array

Abstract

The invention provides a processor comprising a three-dimensional memory (3D-M) array. Logic-based computation (LBC) is replaced with memory-based computation (MBC). The three-dimensional processor comprises a plurality of computation units; and each computation unit comprises an arithmetical logic circuit (ALC) and a 3D-M-based lookup table (3DM-LUT). The ALC performs arithmetic operation on 3DM-LUT data; and the 3DM-LUT is stored in at least one 3D-M array. A programmable computation unit can perform field customization on computation.

Description

technical field [0001] The present invention relates to the field of integrated circuits, and more specifically, to processors. Background technique [0002] Traditional processors use logic-based computation (LBC for short), which is mainly calculated through logic circuits (such as NAND gates, etc.). Logic circuits are suitable for implementing arithmetic operations (such as addition, subtraction, and multiplication), but they are powerless for non-arithmetic functions (such as elementary functions, special functions, etc.). The high-speed and efficient implementation of non-arithmetic functions faces great challenges. [0003] In traditional processors, only a small number of basic non-arithmetic functions (such as basic algebraic functions and basic transcendental functions) can be directly implemented by hardware, and these functions are called built-in functions (built-in functions). Built-in functions are generally implemented by a combination of logic circuits and ...
