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-…
Q1- Write a program in assembly language for the 8085 microprocessor to receive 10 bytes of data via the SID and store it at the memory address (3000H to 3009H) using a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz. When you receive each byte of the required bytes, you must adhere to the following: The bits of two high bits will be received at the beginning of the reception (start bits), after that the data bits will be received, after that the low bit of the stop bit will be received (stop bit). 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 Of+CD!HID+[00 Yes SIDATA Read SID Start Bit?

Q2- Write a program in assembly language for the 8085 microprocessor to receive one byte of data via the SID and store it at the memory address (3000H to 3009H) using a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz . When receive the required bytes, you must adhere to the following: The bits of two high bits will be received at the beginning of the reception(start bits 1 1 ), after that the data bits will be received, after that the low bit of the stop bit will be received (stop bit 0 ). The following flowchart will help you. The solution must be integrated and include the calculation of the baudrate delay time

Assume that A and B are arrays of 64-bit integers, and C and i are 64-bit integers. Assume that all data values and their addresses are kept in memory (at addresses 1000, 3000, 5000, and 7000 for A, B, C, and i, respectively) except when they are operated on. Assume that values in registers are lost between iterations of the loop.
subject: microprocessor and assembly language Data transmission systems and file subsystems often use a form of error detection that relies on calculating the parity (even or odd) of blocks of data. Your task is to create a procedure that returns True in the EAX register if the bytes in an array contain even parity, or False if the parity is odd. In other words, if you count all the bits in the entire array, their count will be even or odd. Preserve all other register values between calls to the procedure. Write a test program that calls your procedure twice, each time passing it a pointer to an array and the length of the array. The procedure’s return value in EAX should be 1 (True) or 0 (False). For test data, create two arrays containing at least 10 bytes, one having even parity, and another having odd parity.

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.
