- Instructions in the LMC are executed in a step-by-step manner starting with 00. a.False b.TrueComputer Science MSP432 Code Composer Studio using ARM-Cortex M4 Assembly. Make a linear congressional generator (Random function generator) as a subroutine, so whenever switch 1 is called (port 6 Bit 0 or P6.0) it outputs a random LED turning on from 6 external LEDS. I just need the "random" Function so I can call it to the subroutine that compares if switch 1 is being pressedwhat is the difference between x84 and x64 bit? with citation
- Create a Verilog module named if2to4 that represents a 2-to-4 binary decoder using an if-elseToggle only bit #4 continuously without changing the rest of the bits of PORTB in BOTH C and assembly language. Assembly language must be for a PIC18Computer Science Write a simple 4-bit number calculator for the HC11 simulator. The calculator should read lower order 4 bits form ports C and D and output the sum to port B. Show the code from the listing file and one screenshot showing ports C, D, and B with the result displayed on port B. (No synchronization is required.)
- When it comes to synchronisation, what exactly does "a race" mean?Using the hardware given to the right, show the addition of two numbers in steps as it would take place. A = 18.625, Show the steps in detail. Also show the contents of different registers (R1, .. R8) and control bits (C1, .. C9). It is noted that Control bits (C, .. C9) could be either 1 or 0 and you can assign the logic levels for particular operations. B = 2.125 You can present your answer preferably in a table.

- The effective address of an operand is the value of its actual address in memory.True or False.LC-3 Fetch a number from memory location 0x3200 and print out the value of the number in decimal. For example at location x3200 the value is 0xFC5D. The two's complement representation of that is 1111 1100 0101 1101 or decimal 931 The program should output that decimal value 931.This is COmputer Architecture! this is about hamming code PLEASE WRITE THE CODE IN MIPS ASSEMBLY LANGUAGE! Assignment for Computer Architecture The assignment is to create a MIPS programs that the determines what the ECC code should be for a given number (an 8-bit byte). ECC Hamming codes are explained on pages 420-424 in your text. The codes you create are to work for 8-bit positive numbers as these are simpler to work with than larger numbers. The program is to request the user to enter a byte of data (a positive integer in the range of 0 to 255 in decimal) and then create the 12-bit Hamming code as described in your text (see above). The program is to then output this (with an appropriate label) in hex. Requirements: Make certain that you have lots of comments in your code as this is in MIPS. Also make the code neat: line up the instruction columns, the register columns, and the comment fields For this assignment, turn in your code, a screenshot showing a working for a test…
