提出了一种利用图形处理器（CPU）进行并行计算的快速多切片图像模拟方法。图像模拟包含多组计算步骤，如傅立叶变换和像素到像素的操作。CPU的效率取决于计算类型。在利用CPU的有效情况下，计算速度比中央处理单元（CPU）快数百倍。进行了并行多层切片的基准测试，并报告了TEM成像、STEM成像和CBD计算等内容的结果。还介绍了仿真软件的一些特点。(C)© 2015 Elsevier B.V.版权所有
A fast multi-slice image simulation by parallelized computation using a graphics processing unit (CPU) has been developed. The image simulation contains multiple sets of computing steps, such as Fourier transform and pixel-to-pixel operation. The efficiency of CPU varies depending on the type of calculation. In the effective case of utilizing CPU, the calculation speed is conducted hundreds of times faster than a central processing unit (CPU). The benchmark test of parallelized multi-slice was performed, and the results of contents, such as TEM imaging, STEM imaging and CBD calculation are reported. Some features of the simulation software are also introduced. (C) 2015 Elsevier B.V. All rights reserved,
