Select the best answer that correctly gives the reason if the above statement is true or false False: The quotient registers needs to be the same size as that of the dividend, as this number could be equal to the dividend False: The quotient width needs to be equal to the sum of the widths of the divisor and the dividend, else there will be an overflow True: The width of the quotient has to be 32 bits no matter the size of the divisor or dividend True: The width of the quotient register is always going to be smaller than the dividend or divisor, since we are dividing. So the quotient register always needs to be smaller in widtharrow_forwardTrue or False: An inclusive OR (OR) instruction generates the value true if either (but not both) data input is true.arrow_forward
- True/False The opcode field of the instruction affects the value of the control signals used to control the dataflow.arrow_forwardJAVASCRIPT description: to make the sum required by the instruction at the top ("Make the number..."), to do this, the players must drag & drop three of the five numbers provided in the yellow circles (two numbers are redundant) into the red circle. The red circle is empty in the beginning and its sum is 0 (not displayed), then each time a number is dropped in the red circle it is added to the sum and the sum is displayed in the red circle. - Randomly generated numbers between 0 and 99 are printed in the yellow circles - The player can drag and drop any number into the red circle. When dropped, this number is removed from the yellow circle- When a number is dropped into the red circle, it is added to the current sum of the numbers dropped in the red circle - Clicking the "Reset" button sets new numbers in the yellow circles and deletes the sum in the red circle - The instructions above the circles ask for the sum of exactly three out of the five random numbers in the yellow…arrow_forwardThe instruction that moves each bit to the right, copies the lowest bit into the Carry flag, and copies the Carry flag into the highest bit position is the one that does this.arrow_forward
