Description: 通信机制: 结构C-S-C
Relay在中间,为console和agent提供双向服务,承担传递console命令和文件到agent, 返回agent命令执行结果与文件开始接收、接收完成信号的功能。此外relay也接受console的控制(与agent类似，通过DosPipe实现).这样的设计是为解决穿透防火墙或路由器(NAT)障碍――由agent发起连接，即从里到外建立一个通道,然后通过relay达到控制目的。通过一个可预设的relay地址序列文件，由agent轮循查找relay；连接建立后，可通过文件传输功能更新该地址序列。
-communication mechanism : C-S-C Relay in the middle, and the agent for the console to provide a two-way service, commitment console commands and transmit documents to the agent, the agent ordered to return to the implementation of the outcome document and the beginning of the reception, the receiving signals function. In addition relay accept the control console (with similar agent, DosPipe achieved). Such a design is to solve penetrate the firewall or router (NAT) obstacles-- initiated by linking agent, from inside out a route, then relay to control purposes. Through a predetermined sequence of relay document addresses from the search agent Round Robin relay; Connections, through file transfer functions to update the address sequence.

Description: 使用DSP软件实现UART功能.一般教科书上提供的UART收发的程序往往是一段采用轮循（Polling）方式完成收发的简单代码。但对于高速的AVR来讲，采用这种方式大大降低了 MUC的效率。在使用AVR时，应根据芯片本身的特点（片内大容量数据存储器RAM，更适合采用高级语言编写系统程序），编写高效可靠的UART收发接口（低层）程序。下面是一个典型的USART的接口程序。-use DSP software UART functions. General textbooks UART transceivers provide the procedure is often used for Round Robin (Polling) transceiver accomplished a simple code. But for the AVR-speaking, the adoption of this approach greatly reduces the efficiency of MUC. The use of AVR, according to the characteristics of the chip itself (large-capacity on-chip data RAM memory, more suitable for the preparation of high-level language system procedures), the preparation of highly efficient and reliable UART interface transceiver (lower) process. Below is a typical USARTs interface procedures.

Description: 看看ARM菜鸟在ARM7上写的操作系统——ARM圈圈操作系统
最近在ADuC7027上写了一个ARM_00_OS，头都写晕了，发上来给大家一起来看看。
任务按优先级调度，如果处于就绪态且优先级最高的任务有两个或更多，则按时间片轮循调度。
支持任务创建、任务删除、内存分配、简单的消息、简单的设备管理、CPU及内存等使用统计等功能。
任务可处于ARM模式或THUMB模式，在创建任务时，要指定任务所处于的模式。

Description: In a preemptive priority based RTOS, priority inversion
problem is among the major sources of deadline
violations. Priority inheritance protocol is one of the
approaches to reduce priority inversion. Unfortunately,
RTOS like uC/OS can’t support priority inheritance
protocol since it does not allow kernel to have multiple
tasks at the same priority. Although it has different ways
to avoid priority inversion such as priority ceiling
protocol, developers still have some difficulties in
programming real time applications with it. In this paper,
we redesign the uC/OS kernel to provide the ability to
support round robin scheduling and implement priority
inheritance semaphore on the modified kernel. As result,
we port new kernel with priority inheritance semaphore to
evaluation board, and evaluate the execution time of each
of the kernel service as well as verify the operations of
our implementation.-In a preemptive priority based RTOS, priority inversionproblem is among the major sources of deadlineviolations.

Description: The main purpose of this project is to add a new scheduling algorithm to GeekOS and to implement a simple synchronization primitive (semaphore). As you might have already noticed, GeekOS uses a simple priority based preemptive Round Robin algorithm. In this project, you will change this to a multilevel feedback scheduling. In addition, you will provide user programs with semaphores, a means to check the system s current time and a mechanism for passing command-line arguments

Description: Round-robin scheduling algorithm is one of the simplest scheduling algorithms. It is designed especially for time-sharing systems. The ready queue is treated as a circular queue. The algorithm assigns a time slice(also called time quantum) to each process in the ready queue in order, handling all processes without priority. A maximum of one time slice is allocated at once. If the remaining request is less than a time slice, only the remaining request time is allocated. Round-robin scheduling is both simple and easy to implement. It is also starvation-free.
