摘　　要：为了降低无线内窥镜系统中的功耗,提出并应用Verilog语言实现了内窥镜图像快速无损压缩。图像压缩算法采用Felics算法。该实现具有复杂度低、功耗低、运算速度快的特点。利用真实内窥镜图像进行压缩实验,获得的平均压缩率为2.26 b/pixel。通过Prime Power测试,在smic 0.13μm工艺和40 MHz的时钟频率的条件下,功耗为6.822 mW,面积为1.15 mm×0.98 mm。该设计适用于低功耗嵌入式应用。In order to decrease the power consumption in the wireless endoscopy capsule, this paper proposes a design of fast lossless compression of endoscope image, which implements Felics algorithm. The design is fast and of low complexity and low power consumption. It can provide a good average compression rate of 2.26 b/pixel when processing endoscopy images. Verified in Prime Power, its power consumption is 6. 822 mW in 40 MHz clock frequency in smic 0. 13 process. And its area is 1.15 mm×0. 98 mm. It＇s suitable for low power embedded application.
