Abstract

For the general application in spacecraft, a proper partition and storage structure is designed. On the basis of it, a novel proper wiring balance and invalid block management algorithm for Nand Flash is developed, which greatly reduce the logical elements requirement for Nand Flash control in FPGA. With the algorithm an common anti-fuse FPGA with 70,000 gates can implement the function of Nand Flash management, which enhanced the reliability. Considered maintainability the flexible logic modules are implemented by software. A data acquisition Device using Nand Flash storage is presented. This paper describes functional structure including software structure and FPGA logic structure of this Device, division and storage structure, the novel proper wiring balance and invalid block management algorithm for Nand Flash, radiation hardened measure, hardware resources requirement. Ideas and strategies of the design are disclosed and a more universal model of key algorithm is presented.
