A processor uses a serial link to communicate with akeyboard for word processing. A typist using thiskeyboard can type at rates peaking at 120 words perminute, where a word is 6 characters (including spacesand punctuation). The characters will be transmittedfrom the keyboard in 8-bit ASCII with one stop bit and no parity.Only consider these and no special characters.The programmer writes setup and polling service routinesbased on a minimum baud rate, but then finds that thekeyboard will only interface at 19.2 Kbaud. Will the pollingservice routine have to change? Why or why not?Baud Rates300600120024004800960019200

Here is an LC-3 assembly language program: .ORIG X3005 A LD R7, D B LD R7, C LD R7, A D LD R7, B HALT .END The following bit pattern is loaded into R7 by one of these instructions: 0010111111111101 What is the label (argument column) of the instruction which loads this value into R7 ?
Computer Science Write an LC3 assembly program to convert a decimal number <20 digit into an ASCII Character using subroutine asking input from the user on the console window. Pre-condition: R0 contains the 2s complement value (0>= value <= 19) Post-condition: R0 contains the 10s digit ASCII character and R1 contains the 1s digit ASCII character.
Perform the following calculation if the maximum memory capacity of the computer is 32 kilobytes and the storage location is the word that is eight bytes in length: 1- The amount of space available. 2- The titles of the first and the last places 3 corresponds to the first binary position.
Booleans are NOT stored as a single bit because simpler for the compiler writer to use a byte rather than a bit a single bit cannot be accessed efficiently on many machines space efficiency is better when using bytes simpler for the programmer to use a byte rather than a bit
Write a procedure, BitComplement, which will complement each bit in the contents of the ax register. For example, after the following code fragment is executed: mov ax, 0011010111000001B call BitComplement 0011 0101 1100 0001 B then the contents of the ax register will be 1100101000111110B (1100 1010 0011 1110 B).

In 8086 ASM 64 bit, how to write assembly code for taking input for a single digit positive number, increment the input number by 2, write the single digit result, decrement the input number by 1 and then finally write the single digit result.
A digital counter is a device that generates binary numbers in a specified count sequence. The counter progresses through the specified sequence of numbers when triggered by an incoming clock waveform, and it advances from one number to the next only during the occurrence of a clock pulse. The counter cycles through the same sequence of numbers continuously so long as there is an incoming clock pulse. You are to build a 3-bit synci. us count-down counter, which is a counter that counts down goes throug..

Write a MIPS assembly program to find the maximum number among three integers. Ask the user to enter the numbers, save the numbers, and perform the operations. Output the max and min numbers. Your solution should work for all input orders (3, 12, 9) or (3, 9, 12), or (12, 3, 9), etc. Example Enter the first number: 3 Enter the second number: 12 Enter the third number: 9 Output (should be exact) The maximum number is 12 and the minimum number is 3.
