| 摘 要： | 根据一种基于分布式算法的通用色彩空间转换方法，优化了色彩空间转换器的硬件结构，并分析了在硬件实现上的量化误差。该结构以流水方式实现，具有较小的延时和较高的数据吞吐率，可以完全满足对色彩空间实时处理的需要。在可接受的误差范围内通过选取适当的小数位数，硬件实现的面积可减小。

| Abstract: | This paper proposes an improvement architecture of distributed arithmetic-based color space converter, and analyses the quantized error of this architecture. This architecture is pipelined, with low latency and high data throughputs, by which the real-time color space conversion can be implemented easily. By choosing proper fractional bit length under acceptable error range, the hardware area of proposed architecture can be reduced by 25%. |
