Q1- Write a program in assembly language for the 8085 microprocessor to send 10 bytes of data located at the memory address (3000H to 3009H) using SOD at a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz. When sending each of the required bytes, you must adhere to the following: The two high bits of the start bits must be sent, after that the data bits are sent, after that the low bit of the stop bit is sent. The following flowchart will help you, but you should notice that this flowchart deals with one byte, and you are required to deal with 10 bytes. The solution must be integrated and include the calculation of the baudrate delay time Transmit No Set up Character Bit Counter Send Start Bit Wait Bit Time Get Character in Accumulator Output Bit Using Do Wait Bit Time Rotate Next Bit in Do Decrement Bit Counter Is It Last Bit? Yes Add Parity if Necessary • Send Two Stop Bits Return (a)
Q2. Interface 4 digit displays (each digit is a 7-segment display) to the 80386DX microprocessor (32 bit data bus and 32 bit address bus) using 8255 PPI. The 8255 should function at I/O addresses that start at 200H. Then write a program to initialize the 8255 and multiplex the 4 digit display where the data, in 7-segment code, that is to be displayed is stored at memory location 2000H: 0100H.
An-Najah National University Department of Computer Engineering Microprocessors (10636322) Assignment # 1 Answer the following: 1- Write an 8086-assembly program that reads only vowels (a, e, i, o, u) from the keyboard (other characters are not excepted) and store them in a character array of 10 bytes long. Vowels entered after the array is full should be discarded. The program should stop reading characters when a 'S' is entered. When the 'S' character is entered, the program should output a new line, followed by the contents of the character array, with a space character between each vowel. 2- Write an assembly code to sort a word array of 50 numbers in ascending order. 3- The perfect number is defined as an integer which is equal to the sum of its divisors. Example: 28 is perfect number because 28 = 1+2+4 +7+ 14. Write an inline assembly e function that will takes an integer number as parameter and check whether it is a perfect number or not. Use the function in complete program. 4-…
