本文讨论了一个单一的精度计算与图形处理单元的声表面波（SAW）器件的有限元法模拟使用分层级联技术（HCT）的适用性。在单精度和双精度下进行了HCT模拟，并比较了所需的计算时间、内存大小和精度。讨论了三种SAW器件结构;（a）42 ° YX-LiTaO 3（42-LT）上的同步谐振器，（b）42-LT上的双模SAW（DMS）滤波器，以及（c）42-LT/Si键合晶片上的同步谐振器。B。它表明，单一的精度使我们能够加倍的计算速度和减半的内存大小可以忽略不计的精度恶化。
This paper discusses the applicability of a single precision computation with a graphics processing unit for the finite elements method simulation of surface acoustic wave (SAW) devices using the hierarchical cascading technique (HCT). The HCT simulation is performed in both single and double precision, and the required computational time, memory size and accuracy are compared. Three SAW device structures are discussed; (a) a synchronous resonator on 42°YX-LiTaO3 (42-LT), (b) a double mode SAW (DMS) filter on 42-LT, and (c) a synchronous resonator on 42-LT/Si bonded wafer. It is shown that the single precision enables us to double the calculation speed and halve the memory size with negligible accuracy deterioration.
