一种面向卫星应用的新型存储器和FPGA设计与实现

可靠性对在轨卫星的安全意义重大。由于空间环境辐射和单粒子效应,卫星系统多次发生在轨异常,对在轨卫星系统工作的连续性、稳定性和安全性造成了严重影响。文章针对卫星在轨空间环境和单粒子问题,提出一种基于铁电材料的高可靠、抗辐射的CPU和FPGA解决方案。一方面,设计了和通用接口兼容的新型铁电存储器,其抗辐射总剂量大于10000Krads（Si）,对单粒子效应几乎具有完全的免疫能力；另一方面,设计了基于铁电编程单元的新型FPGA,该FPGA不需要外部PROM,具有很好的经济性和应用前景。

The Design and Implementation of a Novel Memory and FPGA for Satellite Application

Reliability is vital to the safety of satellite in orbit. Abnormal phenomena frequently occurs in satellites due to the radiation in space environment and SEU （ Single Event Upset） effects, which severely influence the operation continu-ity, stability and security of satellites in orbit. Focused on the above problem of SEU in space environment, this paper pres-ents CPU （ Central processing unit） and FPGA solutions with high reliability and anti-radicalization based on ferroelectric material. On the one hand, a novel ferroelectric random access memory with universal interface is designed and implemen-ted. The total anti-radiation dose of this memory is greater than 10000 Krads （ Si） . Moreover, it is immune to single event upset effects. On the other hand, a new type of FPGA without PROM （ Programmable Read-Only Memory） is designed based on the ferroelectric programming cell, which gives it a bright future for application and extension.
