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:
LoadZero X – this is a conditional instruction, if the AC currently stores the value 0, then load the datum at memory location X

[20 pts] 5- Consider the following hypothetical 1-address assembly instruction called "Store Accumulator Indirect with Post-increment" of the form STA (x)- : M(M(x)) ← AC, M(x) ← M(x)+1 Suppose we want to implement this instruction on the pseudo-CPU discussed in class augmented with a temporary register TEMP. An instruction consists of 16 bits: A 4-bit opcode and a 12-bit address. All operands are 16 bits. PC and MAR each contain 12 bits. AC, MDR, and TEMP each contain 16 bits,...

Also, assume that the control memory is N bits wide (i.e., control field bits + address selection field bits + address-one bits + address-two bits N bits). The control field bits are 15 and there are 15 flags to be monitored. i. How many...

A 5-Stage pipeline is composed
of the following stages Instruction Fetch (IF), Decode (DE),
Execute (EX), Memory Access (ME) and Register Write-back (WB).
Assume the pipeline does not have a branch prediction unit, does
not have superscalar support and does not support out of order
execution. Assume that all memory accesses are in the L1 cache and
therefore do not introduce any stalls. Show a pipeline diagram that
shows the execution of each stage for the assembly code below. Also...
