Description: 用8253作为秒定时器，每0.1秒8253周期定时中断，8253的OUT0接到8259的IRO端，8259向8086产生中断请求，中断类型号为08H。程序开辟秒、分、小时、寄存器单元，秒寄存器每记数满60，分寄存器值加1，同时秒寄存器清0。分寄存器每记数满60，小时寄存器值加1，同时分寄存器清0。秒、分、小时寄存器中的二进制值转换成BCD码后，送6位LED数码管显示。-Using 8253 as a second timer, 0.1 seconds per cycle timer interrupt 8253, 8253 received OUT0 of the IRO-end 8259, 8259 to 8086 generate an interrupt request, interrupt type number 08H. Procedures for opening seconds, minutes, hours, register unit, the number of seconds register each entry age of 60, sub-register value plus 1, and 0 seconds register ching. Sub-registers each counting the age of 60, hour register value plus 1, while sub-register-ching 0. Seconds, minutes and hours registers in the binary value into BCD code, to send six LED digital tube display.

Description: 用8086，8255，8259和8254构造系统实现对指示灯控制。
8255的PA0，PA1,PA2的三位DIP开关，通过DIP开关的闭合状态决定接在
PB口上的八个指示灯之一闪烁。如PA2,PA1,PA0为000时，PB0上所接的指
示灯闪烁，其余灯熄灭。要求闪烁频率为每秒10次。设8259地址为20H和
21H，8255地址为60H～63H，8254地址为40H～43H,时钟频率为50KHz，
8259中断向量号为70H和71H.试设计硬件连接电路，填写中断向量表，编
写全部初始化程序，完成控制程序编写。-8086,8255,8259 and 8254 by tectonic system of light control. 8255 of PA0, PA1, PA2 three DIP switches, DIP switches, through the closed state in the PB I decided to take on one of the eight indicator light flashes. Such as PA2, PA1, PA0 for 000 hours, PB0 on the indicator light flashes then the remaining light extinguish. Requirements flicker frequency of 10 times per second. 8259 address 20H located and 21H, 8255 address 60H ~ 63H, 8254 address 40H ~ 43H, the clock frequency of 50KHz, 8259 interrupt vector number is 70H and 71H. Try to design hardware to connect the circuit to fill in Interrupt Vector Table, the preparation of all the early the beginning of the procedure to complete the preparation of control procedures.

Description: 用减奇数开平方运算
8086/8088指令系统中有乘除法指令但没有开平方指令，因此，开平方运算是通过程序来实现的。用减奇数法可求得近似平方根，获得平方根的整数部分。我们知道，N个自然数中的奇数之和等于N2 ，即：
1+3+5=32
1+3+5+7=16=42
1+3+5+7+9+11+13+15=64+82-Odd square root operation with reduced instruction set in 8086/8088 multiply and divide instructions, but no square root instruction, therefore, square root operation is achieved through the process. Reduction method can be obtained with approximate square root of the odd, the integer part to obtain the square root. We know, N a natural number equal to the sum of the odd N2, namely: 1+3+5 = 32 1+3+5+7 = 16 = 42 1+3+5+7+9+11+13+15 = 64+82
