摘要
为了解决电视广播系统中模拟台标性能不稳定、静止台标显示单一等问题,介绍了一种基于FPGA数字动画台标机的设计方法。详细阐述了动画合成中Flash读控制模块的设计思路,并在Quartus Ⅱ中对设计进行了仿真验证,最后通过硬件测试,证明了该系统设计方法的正确性和可靠性。以及该方法对数字电视广播中数字动画台标机的设计具有普遍适用性。
The design method for the digital motive logo machine based on FPGA is presented to figure out the instability of analog logo and the monotony of static logo. The design process of FLASH read controller in the digital motive logo combiner system is described in detail. The result is simulated with Quartus II. Hardware test shows that this method is correct and reliable. The method is applicable to the system design of the digital motive logo system.
