UCOS2,全称为uC/OS-II,是一款流行的、实时性强、可移植性高的嵌入式操作系统。这个"UCOS2源代码2.91(纯净版)"的资源包含的是该系统的纯源码版本,版本号为2.91,意味着它没有额外的第三方库或特定硬件平台的依赖,更适合开发者进行深入学习和定制。 UCOS2的核心特性包括: 1. **多任务支持**:UCOS2允许同时执行多个任务,通过任务调度器来决定哪个任务应该获得CPU的使用权。每个任务都有其优先级,高优先级任务在没有被阻塞的情况下会抢占低优先级任务。 2. **信号量和互斥锁**:提供同步和资源保护机制。信号量用于控制共享资源的访问数量,互斥锁则确保同一时间只有一个任务可以访问特定资源。 3. **消息队列**:任务间通信的重要手段,一个任务可以发送消息到消息队列,另一个任务则可以从队列中接收消息。 4. **定时器**:可以设置周期性和一次性定时事件,为应用程序提供延时或定期触发功能。 5. **内存管理**:包括动态内存分配和释放,确保有效利用有限的系统内存。 6. **任务切换**:高效的任务切换机制,使得CPU能够在短时间内快速地在不同任务之间切换,从而实现高实时性。 7. **可移植性**:UCOS2设计时考虑了跨平台的兼容性,可以在多种微处理器架构上运行,包括ARM、MIPS、x86等。 源代码的分析和学习对于嵌入式开发人员来说极其重要,因为这有助于理解操作系统的内部工作原理,从而更好地优化应用软件。在"Software"这个文件夹中,可能包含了UCOS2的源码文件、编译脚本、配置文件以及可能的示例项目。开发者可以通过阅读这些源代码,了解任务创建、任务调度、中断处理、内存管理等关键操作的实现细节,并可以根据具体需求进行修改和扩展。 通过学习和实践UCOS2,开发者能够提升在嵌入式系统设计、实时操作系统理解和调试等方面的能力,这对于从事物联网、智能设备、工业自动化等领域的工作至关重要。同时,掌握UCOS2的源代码也有助于开发者过渡到其他类似的操作系统,如FreeRTOS或RT-Thread,因为它们的基本概念和机制是相通的。 "UCOS2源代码2.91(纯净版)"是一份宝贵的教育资源,对于想要深入研究嵌入式实时操作系统的人来说,它提供了丰富的学习材料和实践机会。通过细致地阅读和分析源代码,开发者不仅可以了解UCOS2的内部机制,还能掌握如何有效地利用操作系统来构建高效、可靠的嵌入式应用。

HtmlFormatter 一个纯Java便利类,用于将String格式化为Html String。 它旨在与Android一起使用,但是由于它是纯Java,因此在Android领域之外应该可以正常使用,但是我不确定是否存在这种用例。 例子 。小的() String input = "This is a small string"; String result = HtmlFormatter.from(input).small().getHtmlString(); System.out.println(result); // ----- output ----- // This is a small string .bold()或.strong() input = "This is a bold string"; result = HtmlFormatt

可以即时解锁PDF文件并可以去掉编辑,打印和复制的限制。快速有效地打开加密和有密码保护的PDF文件。这项正在申请Thunder Tables?专利的技术能保证在一分钟之内恢复40位的密码。现代多核电脑提供了多线程低层次代码优化,从而在最好的性能下最快地恢复最复杂的密码。 以下是官网介绍: Recover PDF Passwords and Instantly Remove PDF Restrictions Get access to password-protected PDF files quickly and efficiently! Instantly unlock restricted PDF documents by removing printing, editing and copying restrictions! Advanced PDF Password Recovery recovers or instantly removes passwords protecting or locking PDF documents created with all versions of Adobe Acrobat or any other PDF application. Features and Benefits Supports all versions of Adobe Acrobat, including Acrobat 9 Supports GPU acceleration Supports all third-party products producing PDF files Instantly unlocks PDF documents with printing, copying and editing restrictions Removes “owner” and “user” passwords Recovers passwords to open Supports 40-bit and 128-bit RC4 encryption as well as 128-bit and 256-bit AES encryption Patent-pending Thunder Tables? technology recovers 40-bit passwords in a matter of minutes Dictionary and brute-force attacks with user-defined masks and advanced templates Three editions to satisfy the most demanding and savvy customers Optionally removes JScript code, form fields and digital signatures Batch mode allows automatic processing of multiple files Highly optimized low-level code optimized for modern multi-core CPUs Instant Access to Restricted PDF Documents Remove annoying restrictions from PDF files! Advanced PDF Password Recovery instantly unlocks PDF documents that restrict you of printing, editing or copying of data to clipboard. This is by far the most common protection found in PDF files. If you can open a document without a password, but cannot print it at all or are restricted to low-quality output, or if you cannot copy data to clipboard or cannot edit the document, read no further and get Advanced PDF Password Recovery Standard edition! Passwords to Open What if you can’t open a PDF document at all without knowing the correct password? In that case, you’ll need the password recovery feature found in the Professional and Enterprise editions of Advanced PDF Password Recovery. The PDF format specifies two types of protection: the weak 40-bit and the strong 128-bit encryption. Advanced PDF Password Recovery guarantees the recovery of 40-bit keys by attacking the encryption key instead of attempting to guess the password. While the Professional edition takes up to several days to recover a PDF document protected with a 40-bit key, the Enterprise edition can unlock an encrypted PDF in a matter of minutes! Thunder Tables? Technology (Patent Pending) The unique Thunder Tables? technology developed by ElcomSoft uses pre-computed tables to significantly speed up the recovery of 40-bit keys. The technology is available in the Enterprise edition, and will unlock a protected document in a matter of minutes instead of days. Strong Password Recovery If the PDF is protected with a strong 128-bit or 256-bit key, Advanced PDF Password Recovery performs a range of attacks on the PDF file document in order to obtain the original password. But even then you’re not left without options! Dictionary Attack Most passwords used by living beings are based on a word or phrase. Performing a dictionary attack by attempting different combinations of cases and variations of words and characters before reverting to a comprehensive brute-force attack allows for considerate time savings shall the attack succeed. Brute Force Attack If the password does not fall into any dictionary, Advanced PDF Password Recovery attempts all possible combinations of passwords by performing the brute force attack. The highly optimized low-level code provides the best-in-class performance for the brute-force password recovery. Multi-threaded optimization ensures optimum performance on the modern multi-core CPUs. Additional Notes Mac Computers: Advanced PDF Password Recovery may not run on Mac running Windows 2000/XP/Vista on a virtual machine (using Virtual PC, VMWare, Parallels or other virtualization software). DRM and Third-Party Security Plug-ins: Advanced PDF Password Recovery does not support PDF files protected using Digital Rights Management (DRM) technology or any third-party party security plug-ins such as FileOpen (FOPN_fLock). Version 5.0 works with PDF files created in Adobe Acrobat 9 (with 256-bit AES encryption), with multi-core and multi-processor support and hardware acceleration using NVIDIA cards.
