Calculate the Summation of Numbers using Two Registers
How can you calculate the summation of numbers 1, 2...N using two registers RO and R1?
Is there a specific method to calculate the summation of numbers using the provided registers?
Answer:
To calculate the summation of numbers 1, 2...N using two registers RO and R1, you can use a loop and an accumulator variable.
To calculate the summation of numbers 1, 2...N using two registers RO and R1, you can follow a specific coding technique in assembly language. By using a loop and an accumulator variable, you can efficiently compute the summation of numbers.
Here is an example of a code snippet in the assembly language to calculate the summation of numbers using two registers RO and R1:
MOV RO, N ; move the number N into register RO MOV R1, 0 ; initialize register R1 to 0 (accumulator) LOOP: ADD R1, RO ; add the value in register RO to R1 DEC RO ; decrement the value in register RO by 1 CMP RO, 0 ; compare the value in register RO to 0 JNZ LOOP ; jump to the label LOOP if the value in RO is not zeroIn the above code snippet, the value in register RO is decremented by 1 in each iteration, while the value in register R1 is increased by the decremented value. This process continues until the value in RO becomes zero. The final result, which represents the summation of numbers 1, 2...N, will be stored in register R1.
By understanding and implementing this code logic, you can efficiently calculate the summation of numbers using two registers in an assembly language environment.
