Wavelets have widely been used in many signal and image processing applications. In this paper, a new serial-parallel architecture for wavelet-based image compression is introduced. It is based on a 4-tap wavelet transform, which is realised using some FIFO memory modules implementing a pixel-level pipeline architecture to compress and decompress images. The real filter calculation over 4 · 4 window blocks is done using a tree of carry save adders to ensure the high speed processing required for many applications. The details of implementing both compressor and decompressor sub-systems are given. The primarily analysis reveals that the proposed architecture, implemented using current VLSI technologies, can process a video stream in real time.

RTEMS (Real-Time Executive for Multiprocessor Systems) is a free open source real-time operating system designed for embedded systems. The acronym RTEMS initially stood for Real-Time Executive for Missile Systems, then became Real-Time Executive for Military Systems before changing to its current meaning. RTEMS development began in the late 1980s with early versions of RTEMS available via ftp as early as 1993. OAR Corporation is currently managing the RTEMS project in cooperation with a Steering Committee which includes user representatives.

Visual Basic 6.0可以通过调用API函数格式化一个磁盘，无论是软盘还是硬盘。 打开一个新的项目(工程1) ，如果你没有更改过缺省模式，那么Visual Basic 6.0会自动添加一个form1文件，在form1上添加一个命令控件，将下面的代码拷入。 Option Explicit Private Declare Function SHFormatDrive Lib"shell32"( ByVal Hend AS Long,ByVal Drive AS Long,ByVal FormatID AS Long,ByVal Options AS Long) as Long Private Sub FormatDisk(intDrive as integer,blnQuickFormat as Boolean) dim lngReturn As Long if (blnQuickFormat) then lngReturn= SHFormatDrive(0,intDrive,0&,1&) else lngReturn= SHFormatDrive(0,intDrive,0&,0&) end if end Sub Private Sub Command1_Click() call FormatDisk(0,True) End Sub 运行此程序。 注意FormatDisk函数的第一个变量很重要，他的值是0,1,2时代表格式化的分别是：A、B、C盘。

OpenSS7 This the fourth public release of the OpenSS7 Master Package. See README in the release for a sub-package listing. Most of the sub-packages in the release are production grade for Linux Fast-STREAMS. All existing validation test suites run clean on supported distributions and architectures. It is unlikely that the OpenSS7 Master Package will be released as frequently as before. Sub-packages will be released more often. To rebuild the master package with a new sub-package release, simply replace the directory to which the sub-package belongs with the unpacked sub-package release and then rebuild the master package. This release provides support for recent distributions and tool chains.
