VHDL是Very High Speed Integrated Circuit Hardware Description Language的缩写, 意思是超高速集成电路硬件描述语言。对于复杂的数字系统的设计,它有独特的作用。它的硬件描述能力强,能轻易的描述出硬件的结构和功能。这种语言的应用至少意味着两种重大的改变:电路的设计竟然可以通过文字描述的方式完成;电子电路可以当作文件一样来存储。随着现代技术的发展,这种语言的效益与作用日益明显,每年均能够以超过30%的速度快速成长。 这次毕业设计的内容是在简要介绍了VHDL语言的一些基本语法和概念后,进一步应用VHDL,在MAX+plusII 的环境下设计一个电子钟,最后通过仿真出时序图实现预定功能。电子钟的时间显示用到了七段数码管(或称七段显示器)的电路设计,内部的时间控制输出则用到了各种设计,包括:加法计数器,扫描电路,控制秒、分、时的分频电路,各种数制的转换。

OSCILLATORS are key building blocks in integrated transceivers. In wired and wireless communication terminals, the receiver front-end selects, amplifies and converts the desired high-frequency signal to baseband. At baseband the signal can then be converted into the digital domain for further data processing and demodula- tion. The transmitter front-end converts an analog baseband signal to a suitable high- frequency signal that can be transmitted over the wired or wireless channel.

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.
