I'm trying to create a calculator in MARIE Assembly Language. However, the fact that the calculator stores binary numbers can be utilized in combination with this rotation multiplication in order to multiply any two numbers, given that they will not overflow. The logical structure of the design would then be to store the first value then read the operand to jump to the indicated operation and finally to read in the second value, perform the operation, store it to memory, and then increment the address pointer. However, because this operation takes place at the end of the loop before the program checks if multiplication is complete, there is a possibility that it will be rejecting the multiplication because of an overflowed number that will not be used in the actual process. Find centralized, trusted content and collaborate around the technologies you use most. Use Turbo Debugger to find other errors. It might be difficult to reliably extract the proper bits from the result if you dont convert from ascii before doing anything. You have to figure this out on your own. The outline of this implementation is shown below: While all the other operations are fairly obvious from the flowchart, the implementation of the multiplication function requires further clarification. Ask Question. # - Once an operator is pressed, the operator value is stored in $t5, # - Then, we loop back to the beginning of the program to collect a second operand, # - Next time an operator is pressed, we perform the operation, # - LAST operator pressed is always the one used, # ----------------------------------------------------------------------------------------, # $t2 = $t0 + $t1, when building a number, # $t4 = OPERAND register. The flowchart implementation for multiplication raised an error if the rotate left instruction produced a carry, i.e. Additional functionality for the unsigned value calculator required the results for addition and subtraction remain within 255 and 0 and that the result should show these maxes should an overflow or carry occur.

I'm trying to create a calculator in MARIE Assembly Language. However, the fact that the calculator stores binary numbers can be utilized in combination with this rotation multiplication in order to multiply any two numbers, given that they will not overflow. The logical structure of the design would then be to store the first value then read the operand to jump to the indicated operation and finally to read in the second value, perform the operation, store it to memory, and then increment the address pointer. However, because this operation takes place at the end of the loop before the program checks if multiplication is complete, there is a possibility that it will be rejecting the multiplication because of an overflowed number that will not be used in the actual process. Find centralized, trusted content and collaborate around the technologies you use most. Use Turbo Debugger to find other errors. It might be difficult to reliably extract the proper bits from the result if you dont convert from ascii before doing anything. You have to figure this out on your own. The outline of this implementation is shown below: While all the other operations are fairly obvious from the flowchart, the implementation of the multiplication function requires further clarification. Ask Question. # - Once an operator is pressed, the operator value is stored in $t5, # - Then, we loop back to the beginning of the program to collect a second operand, # - Next time an operator is pressed, we perform the operation, # - LAST operator pressed is always the one used, # ----------------------------------------------------------------------------------------, # $t2 = $t0 + $t1, when building a number, # $t4 = OPERAND register. The flowchart implementation for multiplication raised an error if the rotate left instruction produced a carry, i.e. Additional functionality for the unsigned value calculator required the results for addition and subtraction remain within 255 and 0 and that the result should show these maxes should an overflow or carry occur.
