Q1- Write a program in assembly language for the 8085 microprocessor to send one byte of data located at the memory address (3000H ) using SOD at a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz . When sending the required byte, you must adhere to the following: The two high bits of the start bits(1 1) must be sent, after that the data bits are sent, after that the low bit of the stop bit (0) is sent. The following flowchart will help you. The solution must be integrated and include the calculation of the baudrate delay time

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-…
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.

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).

1. Given the following C code: short ARR [50]; // short is 2 bytes for (short i = 1; i<= 50; i++) ARR [i] = i * i; Convert this code into assembly. Write two versions of the code by using two different addressing modes.
Code required in mips assembly language not a c code required Write a MIPS procedure that takes as its two parameters the starting address of a (zero-terminated) string, and a character c, and removes all instances of the character from the string. Also, write a main program to test your procedure. Your main program should input a string from the user (you can assume that the string will be at most 40 characters, not including the zero byte delimiter), and then prompt for input of a character c. If the character c that the user inputs is the newline character (ascii code 10), your program should terminate. Otherwise, your program should invoke your procedure, output the modified string, and then prompt for input of another character to be removed from the string, continuing in this manner until the input character is the newline character.
