通用串行总线USB(Universal Serial Bus)是一种新型的微机总线接口规范。随着客户对系统数据采集速度要求的不断提高,USB以其使用方便、易于扩展、速度快等优点而越来越多的应用于数据采集系统中。本文介绍了一种基于USB总线的数据采集系统的设计方法,采用PHILIPS公司的USB接口芯片PDIUSBD12与单片机AT89C51进行通信,并和PC机通信而编制出友善的设备应用程序。该系统用传统的USB总线取代了RS232串行总线,通过对USB协议和设备构架的充分理解,对以单片机89C51和USB接口芯片PDIUSBD12为主的数据采集系统进行了硬件设计和软件编程,并在此设计的基础上给出相应的原理图。硬件设计主要解决的是PDIUSBD12和ADC0809与单片机之

Distribution generator Here is a simple generator which can build some distributions with given properties. Distributions generator (compile with -lm) Typical use might be: ./distributions -u -m 1 -M 10 -n 100 -s 500 Generates a distribution of 100 uniform random numbers between 1 and 10, such that the sum of numbers is 500. ./distributions -p -2.2 -m 1 -M 100 -n 200 -s 500 Idem with 200 numbers between 1 and 100 following a power law with exponent -
