摘要
为了便于应用系统在未来进行更新升级和提高解决方案的灵活性、可重用性,相应地提高资源利用率和避免资源浪费,综合采用FPGA和SOPC技术构建了基于NiosⅡ软核CPU的硬盘存储系统的硬件设计方案。使用软核处理器可按功能需求进行配置,易于和其它IP核互连形成完整系统设计,可有效地降低开发周期、缩短上市时间和成本。该设计方案在Al-tera公司的飓风系列FPGA器件中得到了实现并完成验证。目前获得了一定的实际应用且效果良好,具有广泛地应用价值。
To facilitate application system upgrade, avoid waste and improve flexibility and reusability of system solution in embedded system project, FPGA and SOPC technologies are adopted to design hard-disk storage system based Nios Ⅱ soft-core CPU and IP modules. Usage of soft-core CPU can be configured based on function of design demand and easy to connect with other IP （intellectual property） core. It can effectively cut down time to market and cost of design. A successful verification is achieved in Altera＇s Cyclone series FPGA components. The solution of hard-disk storage is applied to special industrial case and got good effect.
