Description

technical field

[0001] The invention relates to the technical field of membrane calculation method and its hardware realization and application, in particular to an improved DND algorithm and its realization method based on FPGA. Background technique

[0002] Membrane computing is a new direction of natural computing and a new branch of molecular computing. It was established by Gheorghe in 1998 propose. Inspired by the structure and function of living cells, membrane computing is a computational model that abstracts and synthesizes the biochemical processes inside cells mathematically. Membrane computing has the remarkable characteristics of great parallelism, non-determinism, and distribution, and it provides a new idea of ​​distributed parallelism for computer information processing. The research results of computational theory show that the membrane computing model (membrane system) has powerful computing functions, and most membrane systems are Turing complete, and c...
