数字图像通信的最广泛的应用就是数字电视广播系统，与以往的模拟电视业务相比，数字电视在节省频谱资源、提高节目质量方面带来了一场新的革命，而与此对应的DVB（Digital Video Broadcasting）标准的建立更是加速了数字电视广播系统的大规模应用。DVB标准选定MPEG—2标准作为音频及视频的编码压缩方式，随后对MPEG—2码流进 ...
This application note covers the design considerations of a system using the performance
features of the LogiCORE™ IP Advanced eXtensible Interface (AXI) Interconnect core. The
design focuses on high system throughput through the AXI Interconnect core with F
MAX
and
area optimizat ...
SRAM-based FPGAs are non-volatile devices. Upon powerup, They are required to be programmed from an external source. This procedure allows anyone to easily monitor the bit-stream, and clone the device. The problem then becomes how can you effectively protect your intellectual property from others ...

A language monitor provides a full duplex communications path between the print spooler and bi-directional printers that are capable of providing software-accessible status information and adds printer control information, such as commands defined by a printer job language, to the data stream s.
DVBstream is based on the ts-rtp package available at
http://www.linuxtv.org. It broadcasts a (subset of a) DVB transport
stream over a LAN using the rtp protocol. There were a couple of
small bugs in the original ts-rtp application, which I have fixed
here.
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 ...
