摘　　要：随着光学遥感相机视频数据实时处理算法复杂度的不断增加,直接使用硬件描述语言进行设计难度越来越大,急需引入一种新流程——通过EDA工具直接将高级语言描述转化为HDL语言描述的RTL代码。本设计选择Catapult C工具完成数字滤波算法从C语言到RTL的设计,最后验证经Catapult设计的RTL代码与C、MATLAB功能一致,经硬件实现后性能相当,设计速度比直接使用硬件描述语言快几倍到几十倍。With the increasing complexity of the algorithm in optical remote sensing camera video real-time data processing,direct design by hardware description languages becoming more and more difficult.By using EDA tools,directly convert complex algorithms describedbyhigh-level language into RTL code as described in HDL language.The design choices of Catapult C tool to complete the digital filtering algorithm from the C language to RTL design.Finally verify designed by Catapult for RTL code with C, Matlab function consistent.After hardware implementation performance,the design speed faster than the direct use of hardware description language several times to several times.
