Cascaded Integrator-Comb filters are a popular choice of filter for use as an interpolator in FPGAs due to their efficient multiplierless design, such as within an on-board satellite communication module. Electronics in space have the problem of being highly susceptible to cosmic radiation, due to the lack of magnetosphere and therefore require some form of protection from Single Event Upsets (SEUs). General techniques exist such as Dual Modular Redundancy (DMR) and Triple Modular Redundancy (TMR), but these may not be desirable due to their large area overhead and power consumption cost. Proposed is a reduced length redundancy technique that offers variable protection for varying power and area resources that could be used with partial reconfiguration to provide dynamically adaptive SEU protection depending on the current environment.

级联积分梳状滤波器是FPGA中用作插值器的一种常见的滤波器选择，这是因为其高效的无乘法器设计，例如在机载卫星通信模块中。由于缺少磁层，太空中的电子产品具有高度易受宇宙辐射影响的问题，因此需要某种形式的保护以防止单事件翻转（SEU）。存在诸如双模块冗余（DMR）和三模块冗余（TMR）之类的通用技术，但是由于它们的大面积开销和功耗成本，它们可能不是理想的。提出了一种长度减少的冗余技术，该技术为可变功率和区域资源提供可变保护，可以与部分重新配置一起使用，以根据当前环境提供动态自适应SEU保护。
