Description: 无沦是用离散逻辑、可编程逻辑，还是用全定制硅器件实现的任何数字设计，为了成功地操
作，可靠的时钟是非常关键的。设计不良的时钟在极限的温度、电压或制造工艺的偏差情况下将
导致错误的行为，并且调试困难、花销很大。 在设计PLD/FPGA时通常采用几种时钟类型。时钟可
分为如下四种类型：全局时钟、门控时钟、多级逻辑时钟和波动式时钟。多时钟系统能够包括上
述四种时钟类型的任意组合。-without the expense of discrete logic, programmable logic, or a full-custom silicon device of any digital design, in order to successfully operate, reliable clock is very critical. The poor design of the clock, the limits of temperature, voltage or manufacturing process of the deviation would lead to wrong behavior, and debugging difficulties, costing much. The design PLD / FPGA usually use several types clock. The clock can be divided into the following four types : global clock, clock gating, multi-level logic clock and volatility clock.

Description: 有m台不同的机器，n个不同的工件。每个工件有多道工序，每道工序由指定的机器在固定的时间内完成。一道工序一旦开始处理，就不能中断。每台机器一次只能处理一道工序。一个调度就是决定每台机器上工序的处理顺序，使得机器完成所有工件的时间最短。具体的，该问题就是要求在满足（1）、（2）两个约束条件的前提下，确定每台机器上工序的顺序，使加工的时间跨度（从开始加工到全部工件都加工完所需要的时间）达到最小。其中，（1）表示工件约束条件：对每个工件而言，机器对它的加工路线是事先确定的；（2）表示机器约束条件：对每台机器而言，一次只能对一道工序进行加工。
任给一个输入实例，能输出最短时间以及每台机器上工序的加工顺序。
能设计出一个用户界面。

Each machine can only handle one time processes. Scheduling is a decision each machine processes the order processing, machinery parts to complete all the shortest time. Specifically, the problem is meeting the requirements (1), (2) 2 restrictive conditions on the premise that each machine to determine the order of the manufacturing process, so that the processing time span (from the beginning of the processing of all jobs have been finished.Chen the time required) to a minimum. Among them, (1) workpiece restrictive conditions : for each workpiece, the machine's processing line it is determined Platform: |

Description: IRP是信息资源规划（Information Resource Planning）的简称。信息资源规划是指对企业生产经营所需要的信息，从采集、处理、传输到使用的全面规划。以制造企业为例，不论产品设计、材料配件采购、加工制造和总装，还是销售和客户服务等等过程，无不充满着信息的产生、流通和运用。要使每个部门内部，部门之间，部门与外部单位的频繁、复杂的信息流畅通，充分发挥信息资源的作用，不进行统一的、全面的规划是不可能的。-IRP Information Resource Planning (Information Resource Planni ng), the abbreviation. Information Resources Planning refers to the production and operation of enterprises the information they need, from the collection, processing, transmission, and use of comprehensive planning. In manufacturing enterprises as an example, whether the product design, material parts procurement, processing and assembly. the sales and customer service process, fraught with all the information generated, circulation and use. Make each department within departments, between departments and external units frequent, complex information-fluent, give full play to the role of information resources, not unified, comprehensive planning is impossible.
