摘要

针对飞行器嵌入式系统对低功耗、高效数据存储解决方案的需求,设计并实现了一种基于GD32微控制器的存储系统,以解决传统基于FPGA的存储系统在高成本、高功耗和技术依赖方面的局限性。本研究采用GD32F470VGT6作为主控单元,结合EXMC接口连接外部存储器NAND Flash,利用USBHS进行数据通信。描述了NAND Flash坏块管理和存储逻辑以及低功耗模式管理。测试结果表明,在执行存储操作时,存储器功耗约为70 mA,平均存储速率达到10.6 MB/s,并且传输数据准确无误。

Abstract

In response to the demand for low-power, efficient data storage solutions in embedded systems for aircraft, this paper presents the design and implementation of a storage system based on the GD32 microcontroller. This approach addresses the limitations of traditional FPGA-based storage systems, particularly regarding high cost, power consumption, and technical dependency. The system utilizes the GD32F470VGT6 as the main control unit, integrates the EXMC interface to connect external NAND Flash memory, and uses USBHS for data communication. This study describes the bad block management and storage logic for NAND Flash, along with the low-power mode management. The test results indicate that the storage system’s power consumption is approximately 70 mA during storage operations, with an average storage rate of 10.6 MB/s, achieving accurate data transmission.
