摘要
介绍了采用流水线技术完成色域扩展的硬件实现方法。色域扩展的整个处理过程是在LCH色彩空间中进行,对亮度L和饱和度C分步处理,设计了一条6级流水线的处理结构,提高了处理数据的吞吐量,及设计的可综合频率。采用了0.18μm的工艺技术,可综合频率达到150MHz,能满足实时处理高清视频数据的要求。同时,采用了灵活的参数配置方式,能方便地应用于不同色调和不同标准的处理,以适应不同色域标准的宽色域高清显示设备的需要。
Implementation method of color gamut extension based on pipeline techniques is introduced. Color gamut extension is accomplished in LCH color space, in which luminance and saturation are processed successively in two steps. A six-stage pipeline architecture is applied to accelerate data processing throughput. In 0.18um. technology, the synthesizable frequency of design is up to 150MHz, thus, processing HD video stream in real-time is achieved, moreover, this design can be applied to wide gamut display with different gamut criteria by initializing parameter memory.
