VHDL 基础语法篇
说明: VHDL 基础语法篇 —— VHDL
VHDL硬件描述语言
1.1 VHDL概述
1.1.1 VHDL的特点
VHDL语言作为一种标准的硬件描述语言,具有结构严谨、描述能力强的特点,由于
VHDL语言来源于C、Fortran等计算机高级语言,在VHDL语言中保留了部分高级语言的原
语句,如if语句、子程序和函数等,便于阅读和应用。具体特点如下:
1. 支持从系统级到门级电路的描述,既支持自底向上(bottom-up)的设计也支持从顶向下
(top-down)的设计,同时也支持结构、行为和数据流三种形式的混合描述。
2. VHDL的设计单元的基本组成部分是实体(entity)和结构体(architecture),实体包含设
计系统单元的输入和输出端口信息,结构体描述设计单元的组成和行为,便于各模块之间数
据传送。利用单元(componet)、块(block)、过程(procure)和函数(function)等语句,
用结构化层次化的描述方法,使复杂电路的设计更加简便。采用包的概念,便于标准设计文
档资料的保存和广泛使用。(VHDL Basic Grammar Paper)

回文判别
实验要求:称正读和反读都相同的字符序列为“回文”,如“abba”和“abccba”是“回文”,“abcde”和“ababab”则不是“回文”,试设计一个算法,判别读入的一个以@为结束符的字符序列是否是“回文”。
实验目的:
1、掌握循环队列的定义及应用;
2、掌握队列的基本操作;
3、进一步熟练掌握栈的基本操作及应用;
4、初步学会解决具体问题的算法设计。-Experimental identification requirements palindrome: that is read and the anti-time sequence of characters are the same as a " palindrome" , such as " abba" and " abccba" is " palindrome" , " abcde" and " ababab" is not " palindrome" and try to design an algorithm to determine a time to @ for the character sequence at the end of it is " Palindrome." The experiment was: 1, master cycle and application of the definition of the queue 2, master the basic operation of the queue 3, and further stack master the basic operation and applications 4, a preliminary settlement of specific issues of the Institute of algorithm design.

nilm-eval-master
说明: NILM-Eval是一个MATLAB框架,允许在不同场景中评估非侵入式负载监控算法,以全面了解其性能.NILM-Eval可以轻松评估多个数据集,住户,数据粒度,时间段和特定算法参数的算法。通过将这些参数封装在配置中。NILM评价仪进一步允许用户轻松地重复其他人执行的实验,评估新数据集上的算法,以及微调配置以提高新算法的性能设置(Nilm-eval is a MATLAB framework that allows evaluation of non-invasive load monitoring algorithms in different scenarios to fully understand their performance. Nilm-eval can easily evaluate algorithms for multiple data sets, households, data granularity, time periods and specific algorithm parameters.By encapsulating these parameters in the configuration.NILM evaluator further allows users to easily repeat experiments performed by others, evaluate algorithms on new data sets, and fine-tune configurations to improve performance Settings for new algorithms)
