The LPC4350/30/20/10 are ARM Cortex-M4 based microcontrollers for embeddedapplications. The ARM Cortex-M4 is a next generation core that offers systemenhancements such as low power consumption, enhanced debug features, and a highlevel of support block integration.The LPC4350/30/20/10 operate at CPU frequencies of up to 150 MHz. The ARMCortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture withseparate local instruction and data buses as well as a third bus for peripherals, andincludes an internal prefetch unit that supports speculative branching. The ARMCortex-M4 supports single-cycle digital signal processing and SIMD instructions. Ahardware floating-point processor is integrated in the core.The LPC4350/30/20/10 include an ARM Cortex-M0 coprocessor, up to 264 kB of datamemory, advanced configurable peripherals such as the State Configurable Timer (SCT)and the Serial General Purpose I/O (SGPIO) interface, two High-speed USB controllers,Ethernet, LCD, an external memory controller, and multiple digital and analog peripherals

The NXP LPC315x combine an 180 MHz ARM926EJ-S CPU core, High-speed USB 2.0OTG, 192 KB SRAM, NAND flash controller, flexible external bus interface, an integratedaudio codec, Li-ion charger, Real-Time Clock (RTC), and a myriad of serial and parallelinterfaces in a single chip targeted at consumer, industrial, medical, and communicationmarkets. To optimize system power consumption, the LPC315x have multiple powerdomains and a very flexible Clock Generation Unit (CGU) that provides dynamic clockgating and scaling.The LPC315x is implemented as multi-chip module with two side-by-side dies, one fordigital fuctions and one for analog functions, which include a Power Supply Unit (PSU),audio codec, RTC, and Li-ion battery charger.

This book evolved over the past ten years from a set of lecture notes developed while teaching
the undergraduate Algorithms course at Berkeley and U.C. San Diego. Our way of teaching
this course evolved tremendously over these years in a number of directions, partly to address
our students' background (undeveloped formal skills outside of programming), and partly to
reect the maturing of the eld in general, as we have come to see it. The notes increasingly
crystallized into a narrative, and we progressively structured the course to emphasize the
?story line? implicit in the progression of the material. As a result, the topics were carefully
selected and clustered. No attempt was made to be encyclopedic, and this freed us to include
topics traditionally de-emphasized or omitted from most Algorithms books.

解壓包包含了C語言入門經(jīng)典教程和Visuak c++軟件
【基本簡介】
Visual C++是一個功能強大的可視化軟件開發(fā)工具。自1993年Microsoft公司推出Visual C++1.0后，隨著其新版本的不斷問世，Visual C++已成為專業(yè)程序員進行軟件開發(fā)的首選工具。
雖然微軟公司推出了Visual C++.NET(Visual C++7.0)，但它的應用的很大的局限性，只適用于Windows 2000,Windows XP和Windows NT4.0。所以實際中，更多的是以Visual C++6.0為平臺。
Visual C++6.0不僅是一個C++編譯器，而且是一個基于Windows操作系統(tǒng)的可視化集成開發(fā)環(huán)境（integrated development environment,IDE）。Visual C++6.0由許多組件組成，包括編輯器、調(diào)試器以及程序向?qū)ppWizard、類向?qū)lass Wizard等開發(fā)工具。 這些組件通過一個名為Developer Studio的組件集成為和諧的開發(fā)環(huán)境。
在Visual C++ 6.0 企業(yè)版的基礎上集成官方的SP6升級補丁制作而成！免序列號，安裝完即可使用，無需再打補丁！
【使用方法】
有些朋友反應在安裝后出現(xiàn) "Error spawning error" 可以看看下面綠色軟件找到的一些解決方案：
點擊VC“TOOLS（工具）”—>“Option（選擇）”—>“Directories（目錄）”重新設置“Excutable Fils、include Files、Library Files、Source Files”的路徑。很多情況可能就一個盤符的不同（例如你的VC裝在C，但是這些路徑全部在D），改過來就OK了。
