1、該P(yáng)ERIPHERAL文件夾包含五個(gè)有關(guān)系統(tǒng)外設(shè)的程序：DEC5502_USB、DEC5502_LED和DEC5502_UART程序。 2、DEC5502_USB程序主要實(shí)現(xiàn)了與PC機(jī)應(yīng)用程序之間的USB通訊，并根據(jù)PC機(jī)傳來(lái)的指令進(jìn)行相應(yīng)的動(dòng)作。 3、DEC5502_UART程序主要完成了利用外擴(kuò)UART（A通路和B通路）與PC機(jī)進(jìn)行數(shù)據(jù)的發(fā)送和接收操作。 4、DEC5502_LED程序通過(guò)配置系統(tǒng)定時(shí)器和系統(tǒng)中斷來(lái)控制指示燈D5和D1，并且通過(guò)D5和D1是否交替閃爍來(lái)達(dá)到測(cè)試系統(tǒng)定時(shí)器和系統(tǒng)中斷的目的。 5、DE5502_SDRAM與EMIF有關(guān)的測(cè)試程序。對(duì)他們的訪問成功與否主要取決于對(duì)EMIF接口的配置，測(cè)試程序配置時(shí)設(shè)為最為可靠的方式，用戶可以根據(jù)相應(yīng)的技術(shù)文檔來(lái)對(duì)EMIF進(jìn)行重新配置，從而提高訪問外擴(kuò)存儲(chǔ)器的速度。

This paper presents a visual based localization mechanism for a legged robot. Our proposal, fundamented on a probabilistic approach, uses a precompiled topological map where natural landmarks like doors or ceiling lights are recognized by the robot using its on-board camera. Experiments have been conducted using the AIBO Sony robotic dog showing that it is able to deal with noisy sensors like vision and to approximate world models representing indoor ofce environments. The two major contributions of this work are the use of this technique in legged robots, and the use of an active camera as the main sensor

fwknop stands for "Firewall Knock Operator" and is an upcoming piece of software that will be released at the DEFCON 12 conference in July, 2004 in Las Vegas. fwknop implements network access controls (via iptables) based on a flexible port knocking mini-language, but with a twist it combines port knocking and passive operating system fingerprinting to make it possible to do things like only allow, say, Linux-2.4/2.6 systems to connect to your SSH daemon. fwknop supports shared, multi-protocol port knock sequences along with both relative and absolute timeouts, and coded port knock sequences encrypted with the Rijndael block cipher.

Cfingerd is a free and secure finger daemon replacement for standard finger daemons such as GNU fingerd or MIT fingerd. It can enable/disable finger service to individual users, rather than to all users on a given host.

CAN1.c and CAN2.c are a simple example of configuring a CAN network to transmit and receive data on a CAN network, and how to move information to and from CAN RAM message objects. Each C8051F040-TB CAN node is configured to send a message when it s P3.7 button is depressed/released, with a 0x11 to indicate the button is pushed, and 0x00 when released. Each node also has a message object configured to receive messages. The C8051 tests the received data and will turn on/off the target board s LED. When one target is loaded with CAN2.c and the other is loaded with CAN1.c, one target board s push-button will control the other target board s LED, establishing a simple control link via the CAN bus and can be observed directly on the target boards.

本題要完成的是一組簡(jiǎn)單C表達(dá)的運(yùn)算。所有表達(dá)式存放在文件 CExpression.txt 中，每個(gè)表達(dá)式一行。每行的長(zhǎng)度不會(huì)超過(guò)80個(gè)字符。文件最后有一個(gè)空行表示結(jié)束。 每個(gè)表達(dá)式，只包含簡(jiǎn)單的整數(shù)變量和限定的一些操作符，表達(dá)式中沒有常量。總共有26個(gè)可能出現(xiàn)在表達(dá)式中的變量，分別命名為 a,b,...,z。每個(gè)變量最多出現(xiàn)一次。26個(gè)變量的初值分別為1，2，...,26。 表達(dá)式中的操作符，包括：兩個(gè)二元操作符 +, -，表示加，減運(yùn)算。例如，表達(dá)式a+c-d+b（即1+3-4+2）的結(jié)果為2。 單獨(dú)一個(gè)-號(hào)不能放在變量前面，表示負(fù)數(shù)。 表達(dá)式中還包含兩個(gè)一元運(yùn)算符：++，--，表示加一和減一運(yùn)算。它們既可以出現(xiàn)在一個(gè)變量的前面、也可以出現(xiàn)在后面。如果出現(xiàn)在變量前面，則表示先對(duì)變量進(jìn)行加一/減一運(yùn)算，然后變量值參與表達(dá)式計(jì)算。如果出現(xiàn)在變量后面，則表示變量的原值參與表達(dá)式計(jì)算，表達(dá)式計(jì)算完之后，變量值加一/減一。 例如，表達(dá)式 -- c + b-- 的結(jié)果為 4, 表達(dá)式計(jì)算完之后， b,c的值分別為1，2 輸出格式要求：輸出直接顯示在屏幕上。對(duì)于每個(gè)表達(dá)式，第一行輸出表達(dá)式的內(nèi)容。第二行輸出表達(dá)式的值，后面幾行輸出參與運(yùn)算的各個(gè)變量的結(jié)果值。
