摘要
主要介绍基于多分辨率重采样算法的图像实时解压缩硬件系统体系结构的设计。首先描述多分辨率重采样算法的解压流程 ;而后提出实现多分辨率重采样解压算法的超大规模集成电路结构 ;最后以可编程序门阵列成功实现。实验表明 ,解压缩硬件系统数据处理速度快 ,满足图像恢复实时性要求。
An image hardware decompression system based on the RBC algorithm is designed. Firstly,the decoding flow of RBC is described in this pap er. Secondly, a VLSI architecture realizing this decoding algorithm is proposed. Finally,the VLSI architecture is implemented in FPGAs,and decompression ASICs ar e produced.Test results show that the data processing speed of the hardware syst em made up of these ASICs is so fast that meet the requirement of real-time imag e decompression.
