JPEG2000是由ISO/ITU-T组织下的IEC JTC1/SC29/WG1小组制定的下一代静止图像压缩标准.与JPEG(Joint Photographic Experts Group)相比,JPEG2000能够提供更好的数据压缩比,并且提供了一些JPEG所不具有的功能[1].JPEG2000具有的多种特性使得它具有广泛的应用前景.但是,JPEG2000是一个复杂编码系统,目前为止的软件实现方案的执行时间和所需的存储量较大,若想将JPEG2000应用于实际中,有着较大的困难,而用硬件电路实现JPEG2000或者其中的某些模块,必然能够减少JPEG200的执行时间,因而具有重要的意义.本文首先简单介绍了JPEG2000这一新的静止图像压缩标准,然后对算术编码的原理及实现算法进行了深入的研究,并重点探讨了JPEG2000中算术编码的硬件实现问题,给出了一种硬件最优化的算术编码实现方案.最后使用硬件描述语言(Very High Speed Integrated Circuit Hardware Description Language,VHDL)在寄存器传输级(Register Transfer Level,RTL描述了该硬件最优化的算术编码实现方案,并以Altera 20K200E FPGA为基础,在Active-HDL环境中进行了功能仿真,在Quartus Ⅱ集成开发环境下完成了综合以及后仿真,综合得到的最高工作时钟频率达45.81MHz.在相同的输入条件下,输出结果表明,本文设计的硬件算术编码器与实现JPEG2000的软件:Jasper[2]中的算术编码模块相比,处理时间缩短了30﹪左右.因而本文的研究对于JPEG2000应用于数字监控系统等实际应用有着重要的意义.

In this paper, we discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, we address different problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All theseproblems are accompanied by an example to have a better idea, and these can be taken care off if thesecoding guidelines are followed. Discussion of all the techniques is beyond the scope of this paper, however,here we try to cover a few of them.

This document was developed under the Standard Hardware and Reliability Program (SHARP) TechnologyIndependent Representation of Electronic Products (TIREP) project. It is intended for use by VHSIC HardwareDescription Language (VHDL) design engineers and is offered as guidance for the development of VHDL modelswhich are compliant with the VHDL Data Item Description (DID DI-EGDS-80811) and which can be providedto manufacturing engineering personnel for the development of production data and the subsequent productionof hardware. Most VHDL modeling performed to date has been concentrated at either the component level orat the conceptual system level. The assembly and sub-assembly levels have been largely disregarded. Under theSHARP TIREP project, an attempt has been made to help close this gap. The TIREP models are based upon lowcomplexity Standard Electronic Modules (SEM) of the format A configuration. Although these modules are quitesimple, it is felt that the lessons learned offer guidance which can readily be applied to a wide range of assemblytypes and complexities.

Methods for designing a maintenance simulation training system for certain kind of radio are introduced. Fault modeling method is used to establish the fault database. The system sets up some typical failures， follow the prompts trainers can locate the fault source and confirm the type to accomplish corresponding fault maintenance training. A training evaluation means is given to examining and evaluating the training performance. The system intuitively and vividly shows the fault maintenance process， it can not only be used in teaching， but also in daily maintenance training to efficiently improve the maintenance operation level. Graphical programming language LabVIEW is used to develop the system platform.
