Web7 dec. 2024 · 1. I have a question about symbol tables. Now according to my textbook the rules of a symbol table are as follows: Find the .ORIG statement, which tells us the address of the first instruction and initialize location counter (LC), which keeps track of the current instruction. For each non-empty line in the program: a) If line contains a label ... WebControl Instructions Used to alter the sequence of instructions (by changing the Program Counter) Conditional Branch • branch is taken if a specified condition is true signed offset is added to PC to yield new PC lthb hitt k 5-9 • else, the branch is not taken PC is not changed, points to the next sequential instruction Unconditional Branch ...
WebIf we set the PC to x3000 and hit "Next", we will execute the AND go to the JSR instruction. Hitting "Next" again will execute everything in the function call, but the simulator won't stop until we reach the NOT instruction, i.e. after the function has returned. Hitting "Next" again will follow the branch and take us to the START label.
