README file for
yampp-3 source code 2001-05-27
This is the current state of the yampp-3 source code, 2001-05-27.
This code is intended to run on Rev. B of the yampp-3 PCB, but can
ofcourse be used on compatible systems as well.
It still uses the "old" song selection system as the yampp-2.
However, the disk handling routines has improved a lot and the
obviosly, the new VS1001 handling has been put in.
The codesize is almost at it s maximum at 1F40 bytes.
A .ROM file is included if you don t have the compiler set up.
For now, the documentation is in the code- mp3 programming cook book in C. README file for yampp-3 source code 2001-05-27 This is the current state of the yampp-3 source code, 2001-05-27.

Description: 1.这个软件可以将一幅BMP图形转换为PCB格式。
2.首先制作一幅 BMP图形，把你需要的汉字或记号包含在内。然后运行本软件，
按下“文件”，调入图形。在“参数”中设置“层”与“线宽”，最后，按下
“转换”就可以了。
3.BMP图形最好是单色的。其实，程序只识别黑色，对其它颜色均不做处理。如
果还要一些特殊效果，请用其它软件完成。
4.制作出来的PCB板大小是BMP图形的大小乘以线宽，单位是mil(100mil=2.54mm)
5.BMP图形的大小不要太大，以免产生的PCB文件过大。一般来说，在200x200以
内比较合适。-1. The software can be a BMP graphics format conversion to the PCB. 2. First produced a BMP graphics, you need to mark or the Chinese characters included. Then run the software, press the "paper" into a graphic. "Parameters" set "layer" and "width" Finally, press the "conversion" on it. 3.BMP monochrome graphics is the best. In fact, the procedure to identify black, the other colors do not handle. If they have some special effect, use other software to complete. 4. Production of PCB size of the BMP graphics to the Oaths linewidth, yes mil units (100mil = 2.54mm) 5.BMP image size should not be too high. to avoid the PCB was too big. Generally speaking, the more appropriate within 200x200.

Description: （1）设计进程控制块PCB表结构，分别适用于优先权调度算法和时间片轮转调度算法。
PCB结构包括以下信息：进程名、进程优先数（或轮转时间片），进程所占用的CPU时间，进程的状态，当前队列指针等。根据调度算法的不同，PCB结构的内容可以作适当的增删。
（2）建立进程就绪队列。对两种不同算法编制入链子程序。
（3）编制两种进程调度算法：a）优先数调度；b）时间片轮转调度。允许用户在程序运行时选择使用某一种调度算法。-(1) design process control block PCB table structure, respectively, applicable to the priority scheduling algorithm and the time slice rotation scheduling algorithm. PCB structure includes the following information: process name, process priority number (or the rotation time slice), the process of occupying CPU time, the process of the state, such as the current queue pointer. According to the different scheduling algorithm, PCB content of the structure can be used for appropriate additions and deletions. (2) the establishment of the process ready queue. Algorithm on two different procedures for the preparation into the chain. (3) the process of the preparation of two scheduling algorithms: a) the number of scheduling priority b) time slice scheduling rotation. Allows the user to choose to use when running a particular scheduling algorithm.
