Our second task is to check the sign bit of a number. There are many ways to do this, but I want the least expensive method in terms of the number of instructions.

I've been working on this project about an assembly-language program that prints the binary version of a four numeral decimal number (such as 3241) to the console, I finished the code but when I run it into LC-3 simulator I get his error "Oh no! You've got an error in your assembly code: at line 16: immediate field is out of range: expected value to fit in 5 bits (i.e., to be between -16 and 15, inclusive), but found 48" I tried to changed the numbers but it didn't work I just need help solving this error so it's able to run into the simulator and prints the output into the console here is the link of the simulator I'm using and my code: link: https://wchargin.com/lc3web/ Code: ;Kevin Hernandez;assembly3.asm A) BINARY TO ASCII;Lavels OPCODE OPERANDS ;Line up the columns .ORIG x3000;data sectionNUMBER .FILL #3241 ;This number is store in NUMBERBIN_REP .BLKW #16 ;This is 16-bit ;code section…
Write a Verilog program (implement Mux 8 to 1 from Mux 2 to 1 and Mux 4 to 1): Assign the input for d7-d0 fix with the value 8'b10110101, use the button on Arty Z7-20 to verify your design.
For example, instruction like this. 0011 0000 0000 0000 ; start at x30000001 001 001 1 00000 ;x3000 set N CC if R1 < 00000 100 0 0000 0001 ;x3001 if N goto x3003 R2+=50000 111 0 0000 0001 ;x3002 Not N goto x30040001 010 010 1 00101 ;x3003 R2 += 5;x3004 done
Kaul is figuring out how to add numbers, however up to this point she isn't doing it accurately. She is adding two numbers an and b utilizing the accompanying calculation: Assuming one of the numbers is more limited than the other, Kaul adds driving zeros so the numbers are a similar length. The numbers are handled from right to left (that is, from the most un-huge digits to the most critical). In the initial step, she adds the last digit of a to the last digit of b and composes their total in the response. At each subsequent stage, she plays out similar procedure on each pair of digits in a similar spot and composes the outcome to the left half of the response. You are given two positive numbers p and q. Print the number r with the end goal that by adding p and r as portrayed above, Kaul will get s

Write a MIPS program that will handle calculating minifloat addition for two numbers using the rules discussed in class and storing each of the parts as a binary integer. To do this, each ‘minifloat’ number will need to be represented (I suggest hard coded) as one register for the sign, one for the exponent part, one for the ‘significand’ (which you then convert to the fraction part). Hard coding means here that you don’t need to read in the 6 parts as user input, just have something like li $s0, 0 li $s1, 12 li $s2, 5 which is equivalent to a minifloat of 0 1101 101 = 1.101 * 2^(12-7) = 1.101*2^5 This means your program will be work with at least 6 registers as variables. For testing, show that your program can correctly calculate the Lab 5 X+Y and A+B and then one other example of your choosing. Don’t worry about special cases of 0 0000 000 or 1 1111 111 or similar, but your program should detect overflow. This will involve a lot of (in your head) jumping back and forth between…
This is Computer Architecture! Instructions: Create a MIPS program that demonstrates that the associative law fails in addition for floating point numbers (single or double precision). You only need to demonstrate it for single precision. Remember the associative law is a + (b + c) = (a + b) + c. The program’s output should look something like the following where the xxx’s are the numbers you chose. The resulting numbers may be different than mine depending on your choice of a, b, and c. Using a = xxx, b = xxx, and c = xxx a + (b + c) = 0 (a + b) + c = 1 The key is to have two of the number large (one positively and one negatively but equal in magnitude) floating point numbers and the third floating point number very small in comparison. Please don't forget to include comments in this code
Translate the following machine code into English. There is no need to trace the execution of the program. Write one English sentence per instruction. For example, for instruction 0xB103, you would write, "Compare register 1 to register 0; if they're the same, jump to address 0x03." 0x10AA 0x2FB0 0xBF00 0x7521 0xA504 0x40E1 0x50FF
A digital clock is to display the month of the year. Because the length of the calendar varies, it is necessary to reset the day display at different points, depending on the month. The calendar month is to be internally present as a 4-bit binary number, that is January = 0001, February = 0010, March = 0011 and so on. As part of the resetting circuit, it is necessary to detect all months having 31 days. Another reset circuit is designed for months with less than 31 days. Note: There are 2 outputs. Design the circuit for each output in SOP format. Hint: There is don't care in this problem
Use the unsigned multiplication algorithm to multiply the unsigned binary numbers 0110 by 1000. Note : For each step show the contents of the registers and the operation performed.

Write an assembly language code on sim8085 for the problem: In a temperature control system, the input received by sensor is 35 degrees Celsius. From the calibration of temperature sensor, it is already known that the sensor shows error of -7 degree Celsius. How will you obtain the true reading in your data record? Please attach the simulation of the code???? Don't copy from anywhere or reject it..
Pick two positive integer numbers. Show that if you multiply them, then you will get a negative integer as your result because of overflow. Therefore, you need to demonstrate what happens when overflow happens with two’s complement integer multiplication. You have a 4-bit processor, and the number representation is two’s complement.
