This application note describes a method for developing block-oriented I/O device drivers for applications that use the DSP/BIOS real-time kernel and includes examples that run with Code Composer Studio v2.1 on the Texas Instruments TMS320C5402 and TMS320C6711 DSP Starter Kits (DSKs). The device driver model presented here has now been superceded with an updated version that supports not only block oriented devices, but also devices such as UARTs, PCI and USB buses and Multimedia cards. Documentation on the updated driver model as well as example drivers and source code can be found in the Device Driver Developer s Kit product now available for download from the TI Developer s Village.

书名：基本商业程序的建模 Essential Business Process Modeling (Paperback) 作者： Mike Havey 出版商：O Reilly 1 edition (August 18, 2005) 内容介绍： Ten years ago, groupware bundled with email and calendar applications helped track the flow of work from person to person within an organization. Workflow in today s enterprise means more monitoring and orchestrating massive systems. A new technology called Business Process Management, or BPM, helps software architects and developers design, code, run, administer, and monitor complex network-based business processes. BPM replaces those sketchy flowchart diagrams that business analysts draw on whiteboards with a precise model that uses standard graphical and XML representations, and an architecture that allows it converse with other services, systems, and users.

计数排序是一个非基于比较的线性时间排序算法。它对输入的数据有附加的限制条件： 1、输入的线性表的元素属于有限偏序集S； 2、设输入的线性表的长度为n，|S|=k（表示集合S中元素的总数目为k），则k=O(n)。 在这两个条件下，计数排序的复杂性为O(n)。 计数排序算法的基本思想是对于给定的输入序列中的每一个元素x，确定该序列中值小于x的元素的个数。一旦有了这个信息，就可以将x直接存放到最终的输出序列的正确位置上。例如，如果输入序列中只有17个元素的值小于x的值，则x可以直接存放在输出序列的第18个位置上。 计数排序算法没有用到元素间的比较，它利用元素的实际值来确定它们在输出数组中的位置。因此，计数排序算法不是一个基于比较的排序算法，从而它的计算时间下界不再是Ω(nlogn)。另一方面，计数排序算法之所以能取得线性计算时间的上界是因为对元素的取值范围作了一定限制，即k=O(n)。如果k=n2,n3,..，就得不到线性时间的上界。

Using the UnderC Tokenizer Class It s often necessary to parse complex text files, where standard i/o is too clumsy. C programmers fall back on strtok(), but this can be tricky to use properly. Besides, you are still responsible for keeping strtok() fed with new input, and I don t like the schlepp. Tokenizer is a text-parsing input stream, modelled after the (undocumented) VCL TParser class, and based on the UnderC tokenizing preprocessor front-end.

The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.
