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.

Software Engineering is a discipline applied by teams to produce high-quality, large-scale, cost-effective software that satisfies the users’ needs, and can be maintained over time Software Development is a weaker term where standards, tools, processes, etc. may not be applied

All 3G and GSM specifications have a 3GPP specification number consisting of 4 or 5 digits. (e.g. 09.02 or 29.002). The first two digits define the series as listed in the table below. They are followed by 2 further digits for the 01 to 13 series or 3 further digits for the 21 to 55 series. The term "3G" means a 3GPP system using a UTRAN radio access network the term "GSM" means a 3GPP system using a GERAN radio access network. (Thus "GSM" includes GPRS and EDGE features.)

蓝牙协议This specification describes the Audio/Video Control Transport Protocol (AVCTP), which is used to transport command and response messages for controlling Audio Video features in conformant devices. This protocol enables a device to support more than one control profile at the same time each supported profile shall define its own message formatting and/or usage rules.
