this a pack include source code for quartus 2. It is an implementation of the LC2. The LC-2 computer is described in Introduction to Computing Systems from Bits & Gates to C & Beyond by Yale Patt and Sanjay Patel, McGraw Hill, 2001. The LC2 mode

该项目的目的是设计和实施，为的沟通通过其JTAG接口和控制是通过设置断点和寄存器和存储器访问程序的执行能力ATmega644调试。-The purpose of this project was to design and implement a debugger for the ATmega644 that communicated through its JTAG interface and was capable of controlling program execution by se

可能是流传最广、最为经典的样板作品，Pascal语言之父、图灵奖获得者Niklaus Wirth在其名著Algorithms + Data Structures = Programs第5章给出的一个递归下降预测分析器实现。毫无疑问，它是用Pascal语言编写的。该编译器生成的目标语言是p-code，一台p- code虚拟机有3个寄存器（程序计数器、基本寄存器和栈顶寄存器）和8条指令（每条指令有多种形式）。-May be the most widely accepted model for the

volatile的作用volatile的本意是“易变的” 由于访问寄存器的速度要快过RAM，所以编译器一般都会作减少存取外部RAM的优化。比如： -The role of volatile volatile are intended to be " volatile" registers as faster access than RAM, so the compiler will generally be optimized to reduce access to

The C project about msp430g2553,describes the msp430g2553 and 12864, including the use of various registers and gives a programs, counting experiments.
