在顺序存储结构中，利用编号表示元素的位置及元素之间孩子或双亲的关系，因此对于非完全二叉树，需要将空缺的位置用特定的符号填补，若空缺结点较多，势必造成空间利用率的下降。在这种情况下，就应该考虑使用链式存储结构。-Storage structure in order to use the element number that the location and elements of the relationship between children or parents, so for non-complete binary tree, the location of the vacancy will be required to use specific symbols to fill the vacancy if more nodes, it is bound to cause decline in utilization of space. In this case, we should consider the use of the structure of chain stores.

本程序实现FCFS先来先服务，SPF短进程优先，FPF_Reaved抢占式高优先级，TimePiece时间片轮转这四种进程调度算法。
程序运行时根据提示选择相应进程调度算法，然后调用函数GetRandProc(LPVOID lpParam)（程序专门为该函数开辟新的线程）产生随机进程并将其插入到就绪队列中然后再用相应的进程调度算法调度进程运行。
-the program FCFS first-come first-serve, SPF short process priority, Preemptive FPF_Reaved high-priority, TimePiece time to rotate the four-process scheduling algorithm. Running time prompted the selection process scheduling algorithm, then the function call GetRandProc (LPVOID lpParam) (specialized procedures for the letter several open up new threads) random process and will be inserted into its place queue Then the corresponding process scheduling algorithm scheduling The process runs.

ST7787 芯片的SPEC，比亚迪2.4inchLCM的SPEC。The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and
320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial
Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display
data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to
minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal,
it is possible to make a display system with the fewest components.-ST7787 chip SPEC, BYD 2.4inchLCM the SPEC. The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD.
