針對目前使用的RS232接口數(shù)字化B超鍵盤存在PC主機(jī)啟動時不能設(shè)置BIOS，提出一種PS2鍵盤的設(shè)計方法。基于W78E052D單片機(jī)，采用8通道串行A/D轉(zhuǎn)換器設(shè)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(fā)送，正交編碼器信號通過XC9536XL轉(zhuǎn)換為單片機(jī)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(jié)果表明，在滿足開機(jī)可設(shè)置BIOS同時，又可實現(xiàn)超聲特有功能，不需要專門設(shè)計驅(qū)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.

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 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.

design LP,HP,B S digital Butterworth and Chebyshev
filter. All array has been specified internally,so user only need to
input f1,f2,f3,f4,fs(in hz), alpha1,alpha2(in db) and iband (to specify
the type of to design). This program output hk(z)=bk(z)/ak(z),k=1,2,...,
ksection and the freq.

基于verilog HDL的自動售貨機(jī)控制電路設(shè)計:
可以對5種不同種類的貨物進(jìn)行自動售貨,價格分別為A=1.00,B=1.50,C=1.80,D=3.10,E=5.00 。售貨機(jī)可以接受1元,5角,1角三種硬幣(即有三種輸入信號IY,IWJ,IYJ),并且在一個3位7段LED(二位代表元,一位代表角)顯示以投入的總錢數(shù)，最大9.90元，如果大于該數(shù)值，新投入的硬幣會退出,選擇貨物的輸入信號Ia,Ib,Ic,Id,Ie和一個放棄信號In,輸出指示信號為 Sa, Sb ,Sc ,Sd, Se 分別表示售出相應(yīng)的貨物,同時輸出的信號yuan, jiao代表找零,相應(yīng)每個脈沖代表找零相應(yīng)的硬幣，上述輸入和輸出信號均是一個固定寬度的脈沖信號。
