基于單片機的數字化B超鍵盤設計

針對目前使用的RS232接口數字化B超鍵盤存在PC主機啟動時不能設置BIOS，提出一種PS2鍵盤的設計方法。基于W78E052D單片機，采用8通道串行A/D轉換器設計了8個TGC電位器信息采集電路，電位器位置信息以鍵盤掃描碼序列形式發送，正交編碼器信號通過XC9536XL轉換為單片機可接收的中斷信號，軟件接收到中斷信息后等效處理成按鍵。結果表明，在滿足開機可設置BIOS同時，又可實現超聲特有功能，不需要專門設計驅動程序，接口簡單，成本低。 Abstract: Aiming at the problem of the digital ultrasonic diagnostic imaging system keyboard with RS232 interface currently used couldn?蒺t set the BIOS when the PC boot， this paper proposed a design method of PS2 keyboards. Based on W78E052D microcontroller，designed eight TGC potentiometers information acquisition circuit with 8-channel serial A/D converter， potentiometer position information sent out with keyboard scan code sequentially.The control circuit based on XC9536 CPLD is used for converting the mechanical actions of the encoders into the signals that can be identified by the MCU， software received interrupt information and equivalently treatmented as key. The results show that the BIOS can be set to meet the boot， ultrasound specific functionality can be achieved at the same time， it does not require specially designed driver，the interface is simple and low cost.

98年全國大學生數學建模競賽B題“水災巡視問題”

98年全國大學生數學建模競賽B題“水災巡視問題”，是一個推銷員問題，本題有53個點，所有可能性大約為exp(53),目前沒有好方法求出精確解，既然求不出精確解，我們使用模擬退火法求出一個較優解,將所有結點編號為1到53,1到53的排列就是系統的結構,結構的變化規則是:從1到53的排列中隨機選取一個子排列,將其反轉或將其移至另一處,能量E自然是路徑總長度。具體算法描述如下：步1：設定初始溫度T，給定一個初始的巡視路線。步2 ：步3 --8循環K次步3：步 4--7循環M次步4：隨機選擇路線的一段步5：隨機確定將選定的路線反轉或移動，即兩種調整方式：反轉、移動。步6：計算代價D，即調整前后的總路程的長度之差步7：按照如下規則確定是否做調整：如果D0,則按照EXP(-D/T)的概率進行調整步8:T*0.9-->T,降溫

This project attempts to implement a Database using B+Tree. The project has developed a DATABASE SYSTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.

Verilog HDL: Magnitude For a vector (a,b), the magnitude representation is the following: A c

Verilog HDL: Magnitude For a vector (a,b), the magnitude representation is the following: A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.
