Application-specific data processing units (DPUs) are commonly adopted for operational control and data processing in space missions. To overcome the limitations of traditional radiation-hardened or fully commercial design approaches, a reconfigurable-system-on-chip (RSoC) solution based on state-of-the-art FPGA is introduced. The flexibility and reliability of this approach are outlined, and the requirements for an enhanced RSoC design with in- flight reconfigurability for space applications are presented. This design has been demonstrated as an on-board computer prototype, providing an in-flight reconfigurable DPU design approach using integrated hardwired processors.  相似文献

A detailed experiment of 1-pixel bit reconfigurable ternary optical processor (TOP) is proposed in the paper. 42 basic operation units (BOUs) and 28 typical logic operators of the TOP are realized in the experiment. Results of the test cases elaborately cover the every combination of BOUs and all the nine inputs of ternary processor. Both the experiment process and results analysis are given in this paper. The experimental results demonstrate that the theory of reconfiguring a TOP is valid and that the reconfiguration circuitry is effective.  相似文献

为了提高可重构频罩滤波器的设计结果,提出了一种基于二阶锥优化的改进设计方法.不同于传统的将所有子滤波器分开设计的方法,该方法将所有期望的设计模式纳入到设计目标中来联合设计所有子滤波器.首先,单独设计所有子滤波器以获得一个初始结果;然后,迭代求解一个二阶锥优化问题,以更新初始结果.通过一个设计实例来验证所提出算法的有效性.仿真结果表明,相比于传统的设计方法,将所有子滤波器联合设计能够显著降低minimax准则的设计误差.  相似文献
