摘要:

随着FPGA的低成本化和整合资源的不断增强,FPGA在整个嵌入式市场中的份额在不断增加。基于FPGA的NiosII软核以其高度的设计灵活性和完全可定制性在现今电子产品设计及工业控制中扮演着重要的角色。此外,以SD卡为代表的大容量存储卡成为消费电子类产品最重要的存储媒体。基于NiosII软核处理器来读写SD卡的接口设计在诸多电子系统中的使用也愈来愈多。文中给出了基于NiosII软核处理器的SD卡接口设计方案,并介绍了NiosII的驱动架构,给出SD存储卡在NiosII软核上的驱动程序设计

Abstract:

With low-cost FPGA and its growing integration of resources,the share of FPGA in the entire embedded market continues to increase. FPGA-based Nios II soft core for its high degree of design flexibility and full customizability plays an important role in today's electronic products and industrial control design. In addition,the SD mass storage card becomes the most important media in consumer electronics products. SD card reader interface design based on the Nios II soft core processor is more and more used in many electronic systems. In this paper,proposed the Nios II soft core processor based SD card interface design and Nios II driver architecture. In addition, presented the design of the SD memory card driver based on Nios II soft core
