Description: Buddy（伙伴）算法每次分配包含一个或者多个物理页面的内存块，页面以2的次幂的内存块来分配。首先搜寻满足请求大小的页面，它从满足当前申请大小的Buddy数据结构的m_ freePages域着手沿链来搜索空闲页面。如果没有这样请求大小的空闲页面，则它搜索两倍于请求大小的内存块。这个过程一直将持续到所有的Buddy 被搜索完或找到满足要求的内存块为。如果找到的页面块大于请求的块则对其进行分割以使其大小与请求块匹配。由于块大小都是2的次幂所以分割过程十分简单：空闲块（低地址）被连进相应大小的队列而这个页面块被分配给调用者。 释放时，先检查该块的伙伴的使用情况，如果没有被使用，则合并这对Buddy，再检查该两倍大小的块的Buddy，一直持续到合并后的块没有Buddy为止，并将之链到该大小的freepage队列中。-Buddy (partners) each allocation algorithm contains a number of physical pages or blocks of memory, two pages to the Powers of the block of memory to allocate. First of all search requests to meet the size of pages, from the application to meet the current size of the data structure Buddy 8 freePages domain proceed along the chain to search leisure pages. If no such request size spare pages, which then search request twice the size of a memory block. This process has to continue until all the Buddy Search End or were found to meet the requirements for the memory block. If found in the pages block greater than the requested block is divided in its size and make it the request block matching. As pieces are the two Powers So segmentation process is very simple : free block (low-address) was e

这是我在去年年底利用业余时间做的一个鞋塑企业的计件工资系统。由于本人技术有限，请各位下载看过源码的同仁能给些建议，谢谢了。
我的Email:softboy@vip.sina.com
QQ:9844389 验证信息：DFW,谢谢了！以下我说一下使用源码注意项：
1、Windows2000 Professional SP3、DELPHI 6.0、SQL Server2000的开发环境；
2、开发目录为：D:PieceRate，数据库备份存放于Data目录中，还原SQL Server后名为PieceRate；
3、目前客户3站点在使用，初次运行时服务器名、客户机名的设置大家应该会吧，不会就QQ吧。
4、里面有大量数量，数据日期为2003年1月份的，所以大家查看统计时要注意日期，如果统计全部人员的数据耗时会比较长一些；
5、统计大部分使用了存储过程；
6、使用了Devexpress Quantum、LxMenu、Reportmachine等控件；
7、二用户密码均为1；
8、此源码献给DELPHI最初级者学习使用，如果您认为您是高手或看过源码后觉得垃圾一堆，您可立即删除。但也欢迎您给我建议。
9、谢谢! -This is my last year to use their spare time to do a plastic shoes enterprise piece-rate wage system.

Description: sdram控制器
这里考虑将SDRAM控制器结合目前项目开展来做相应的模块，而不做SDRAM通用控制器，这样也是考虑了FPGA的器件资源而采取的措施。同时编写的逻辑简单，没有多余的逻辑资源有利于提高控制器的速度，满足最后的设计要求。-SDRAM controller here consider SDRAM controller current projects do the corresponding module, but not so common SDRAM controller, as well as consider the FPGA device resources and the measures taken. While the preparation of simple logic, the logic is no spare resources to improve the speed controller to meet the final design requirements.

Description:
1． 存储管理采用可变分区方式。可变分区方式是按作业需要的主存空间大小来分配分区的。当作业装入主存时，根据主存的需要量察看有无足够的空间分配，若有，则按需要量分配一个分区给该作业；若无，则作业不能装入。随着作业的装入，撤离，主存被分成许多分区，有的占用，而有的是空闲的。
2． 存储分配分别采用首次适应算法、最佳适应算法和最差适应算法。
3． 当一个新作业要求装入主存时，查找空闲区表，从中找出一个足够大的空闲区。若找到大于作业需要量的空闲区，则把它分成二部分，一部分为占用区，另一部分又成为一个空闲区。
4． 当一个作业撤离时，归还的区域如果与其他空闲区相邻，则应合并成一个较大的空闲区，登在空闲区表中。
5． 本实验是模拟主存分配，按照存储分配算法设计主存分配和回收程序，并不实际启动装入作业。
-1. Storage management through the use of Variable way. Variable area by way of operational requirements is the main deposit size space to be allocated to the district. When loading operations at the main deposit, the owners of the deposit requirement to see whether enough space allocation, if so, according to a regional distribution requirements for the operation; If no, operation can not be loaded. With the loading operations, evacuation, the main deposit is divided into many districts, some occupied, while others are idle. 2. Storage allocation were used to adapt the first algorithm, the best adaptation algorithm and the worst adaptation algorithms. 3. When a new operational requirements of the main deposit loaded when you spare the District table to find a large enough free zone. If fou
