MARIE Assembly Code Problem
For the following problem, please create new MARIE instructions by providing the full MARIE RTN (register transfer notation) for the described operation. Your answer should include the fetch, decode, operand fetch (if necessary), execution and store result (if necessary) stages. When you see X in these instructions, this is a main memory address (the last 12 bits of the 16-bit instruction) – refer to this as IR[11..0] and not X.
Problem:
ClearIndirect X – X is a pointer to a datum, place 0 at the memory location pointed to by the address stored in X. This requires loading X, which itself is an address, and then using the address to store 0 there. Do not store 0 at X itself.
