An approximation for fast digital hologram generation is implemented on a central processing unit (CPU), a graphics processing unit (GPU), and a multi-GPU computational platform. The computational performance of the method on each platform is measured and compared. The computational speed on the GPU platform is much faster than on a CPU, and the algorithm could be further accelerated on a multi-GPU platform. In addition, the accuracy of the algorithm for single- and double-precision arithmetic is evaluated. The quality of the reconstruction from the algorithm using single-precision arithmetic is comparable with the quality from the double-precision arithmetic, and thus the implementation using single-precision arithmetic on a multi-GPU platform can be used for holographic video displays.
一种用于快速数字全息图生成的近似方法在中央处理器（CPU）、图形处理器（GPU）和多GPU计算平台上实现。测量并比较了该方法在每个平台上的计算性能。GPU平台上的计算速度比CPU快得多，并且该算法在多GPU平台上可以进一步加速。此外，还评估了该算法在单精度和双精度运算中的准确性。使用单精度运算的算法重建质量与双精度运算的质量相当，因此在多GPU平台上使用单精度运算的实现可用于全息视频显示。
