An implementation scheme of IJF coding based on FPGA is proposed, which has the features of highly integration, flexible configuration, stable performance.
Accuracy analysis and stability analysis indicate that this scheme has two order accuracy and is unconditionally stable when grid size is constant.
文中的精度分析和稳定性分析表明该差分格式在等步长条件下具有二阶精度、无条件稳定。

At the same time, based on the result, it is concluded that the upwind finite difference scheme for solving the one dimensional heat transfer equation for SG is stable.
