基于μc／os—II的多窗口显示屏控制器设计
Design of Multi-window Screen Controller Based on μC/OS -II
摘要
Abstract
The multi-task management operation mode of the μC/OS-II real-time operating system is used to control the multi-window display screen, with the video data of each window managed by thread. Nios II 32-bit processor forms the nucleus of the hardware system of the display controller, and the random display of each window is controlled by the software system. The hardware system of the display controller is achieved on a FPGA chip, and the SOPC Builder software is used to custom IP core needed by the system. The rela- tive insufficiency problem of FPGA internal resources is resolved by expanding memory equipment to realize mass storage of video data. The grayscale control of video data is implemented, data processing is decreased and the complexity of the control system is reduced through the reconstruction of video data and reasonable organization of data storage mode.关键词
