本论文主要介绍了JPEG的编码和解码过程。该程序的编码部分能把一张BMP格式的图象进行JEPG编码,压缩成以二进制形式保存的文件;通过相应的解码程序又可以把图象解压缩出来。在图象传送过程中,我们经常采用JPEG格式对静态图象进行编码。JPEG基本系统是一种有损编码,无法完全恢复出原图象,信息有一定的丢失,称为有损压缩 ...

1)I:初始化(Initialization)。从终端读入电文,写到tobetrans文件中,统计电文的字符集合和对应的权值集合,建立哈夫曼树,并将哈夫曼树存于文件hfmtree中。
(2)C:编码(Coding )。利用已建好的哈夫曼树(如不在内存,则从文件hfmtree中读入),对文件tobetrans中的正文进行编码,然后将结果存入文件codefile中。

D169 Demo - DMA0 Repeated Burst to-from RAM, Software Trigger
Description A 32 byte block from 220h-240h is transfered to 240h-260h
using DMA0 in a burst block using software DMAREQ trigger.
After each transfer, source, destination and DMA size are
reset to inital software setting because DMA tran ...

The main file in this list of programs is "vblast.m". Type "help vblast" on the command line for details.Study the coding
by stepping through the program. These programs require around 5000 packets for reasonable plotting accuracy.This has been
implemented for a 2x2 system. The reader can program o ...

This chapter contains sample programs for determining capacity. The reader is advised to go through the coding. The
file "capacity_water.m" is for measuring the waterfilling capacity. It should be made to work with a file similar to
"capacity_plot_main.m". The latter file deals with all the other c ...

This project should serve as an "easy start" with embOS.
All pathes are relative to the project file.
You should therefor be able to copy the
entire directory (including all subdirectories)
to any location on your harddrive.

With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common resear ...
