摘要:

针对采用传统硬件方法实现JPEGLS无损图像压缩算法时延时较多、实时性较差的问题,文中提出了一种基于FPGA的全流水线结构来实现JPEGLS算法。该结构以提高最大吞吐量为主要目标,通过多级流水线降低每一级运算的延迟,大幅提高了压缩算法的实时性,硬件电路操作频率可达120 MHz。

关键词: 全流水线, 无损图像压缩, 大吞吐量, FPGA

Abstract:

The traditional hardware implementation of JPEGLS lossless image compression algorithm suffers poor realtime performance. This paper presents a fullypipelined structure based on FPGA to achieve the JPEGLS algorithm. The structure reduces the delay of every step through Multistage pipeline to improve maximum throughput as well as the realtime of the compression algorithm, making hardware circuit operating frequencies up to 120 MHz.

Key words: fully pipeline, lossless image compression, high throughput, FPGA
