Imagine that you are at the beginning of the LOOP (#11). Assume that the values of nl and n2 are 6 and 2. The variables n1, n2, and q are stored at registers 16, 17, and 18, respectively. Code Line # A- D- M- ALU Data Instruction Program Control/Address/ (starting from register register Register memory Memory Counter Data bus (12) The A- NA M reg- ΝΑ ister The data register is set points The program counter is set to PC++ -> to 16 to The in- struction memory input is set to address of #13 the memory that stores The control bits are sent to A register to load the value 16. The address of vari- able nl is put into the address bus to access the memory location. The control bits are sent to the PC to in- crement its value by 1. mem- ory is ac- cessed to read RAM 16 that stores the value of nl ad- dress of #13 in- the vari- struction able nl, RAM[16] #21 #22 #23 Create the given Table 1 in a Word document (or a similar text editor) and then fill in the information for lines 13 - 23. Hint: It may be useful to run this code in the CPU Emulator and examine what happens at each step. #1 @RO //set RO #2 D=M #3 @nl #4 M-D// nl-RO #5 @R1 //set R1.
