摘要
基于μC/OS-Ⅱ实时操作系统实现多任务管理运行模式,采用NiosII32位处理器作为LED显示屏控制系统的核心,控制单屏幕多窗口任意显示。整个控制系统在一片FPGA上实现,使用SOPCBuilder软件定制集成IP核,通过外扩存储设备实现数据的海量存储,解决了FPGA内部资源相对不足的问题。同时,合理组织数据存储方式,降低了数据处理和控制系统的复杂度。
Muhitask management operating mode is realized based onμC/OS-Ⅱ, using Nios Ⅱ 32-bit processor as the core of the LED display control system to display contents in multi windows on a single screen. The whole system is integrated on a single FPGA, using SOPC Builder to customize the IP core and extending peripheral memory to realize mass storage. The problem of resource deficiency within FPGA is solved. Also, reasonable organization of data storage reduces the complexity of both data processing and the control system.
