用于求解 3D 有限元分析的逐元素预条件共轭梯度 (PCG) 迭代求解器已在基于 FPGA 的 32 位浮点可重构计算机中实现。选择算法公式是为了优化与 FPGA 平台功能的匹配。与在快速 PC 上运行的优化 64 位软件版本相比，它的速度可提高约 40 倍。
An element-by-element preconditioned conjugate gradient (PCG) iterative solver for the solution of 3D finite element analysis has been implemented into a FPGA-based 32-bit floating-point reconfigurable computer. The algorithm formulation has been chosen in order to optimize the match with the capabilities of the FPGA platform. It is capable of giving a speed-up of about 40 times compared to an optimized 64-bit software version running on a fast PC.
