提出了一种基于伊辛模型基态搜索和存储单元概率行为的计算结构。为了提高计算机的性能，提出了一种空间计算体系结构，该体系结构将Ising模型定义为软件和硬件之间的接口。在伊辛模型中，各种问题都可以用空间参数来表示。利用基于存储单元阵列的硬件来搜索Ising模型的基态。记忆细胞之间的相互作用产生了向低能量的状态过渡，并且记忆细胞在低电压下稳定性的随机性有助于摆脱局部最小值。仿真结果表明，所提出的体系结构能够解决因式分解和旅行商问题等实际问题。
A new computing architecture based on a ground-state search of the Ising model and the probabilistic behavior of a memory cell is proposed. To improve computer performance, a spatial computing architecture that defines an Ising model as the interface between software and hardware is proposed. Various problems can be represented as a spatial parameter in the Ising model. A memory-cell-array-based hardware is utilized to search for the ground state of the Ising model. The interaction between memory cells produces a state transition to lower energy, and the randomness of memory-cell stability at lower voltage helps escape from a local minimum. It was verified by simulation that the proposed architecture can solve practical problems such as factorization and the traveling-salesman problem.
