Welcome to PMOS. PMOS is a set of modules, mostly written in Modula-2, to support multitasking. PMOS was designed primarily with real-time applications in mind. It is not an operating system in the conventional sense rather, it is a collection of modules which you can import into your own programs, and which in particular allow you to write multi-threaded programs.

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.

As of UnZip 5.42, this source has been removed from Info-ZIP s UnZip source distribution because of its conflicting copyright. There are no plans to ever rewrite this code from scratch, because the unreduce algorithm was never used in the "real" world.

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.

操作系统的选择是由嵌入式系统的需求决定的。简单的说就是，中小型控制系统可充分利用uC/OS-II小巧且实时性强的优势，如果开发PDA和互联网连接终端等较为复杂的系统则uClinux是不错的选择。

多任务系统中，内核负责管理各个任务，或者说为每个任务分配CPU时间，并且负责任务之间的通讯。内核提供的基本服务 以使用实时内核可以大大简化应用系统的设计，是因为实时内核允许将应用分成若干个任务，由实时内核来管理它们。内核 用程序的额外负荷，代码空间增加ROM的用量，内核本身的数据结构增加了RAM的用量。但更主要的是，每个任务要有自己的 吃起内存来是相当厉害的。内核本身对CPU的占用时间一般在2到5个百分点之间。 UC/OS-II有一个精巧的内核调度算法,实时内核精小，执行效率高，算法巧妙,代码空间很少。
