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...

Suppose that an 8-bit microcontroller has a 16-bit stack pointer and uses a 16-bit register to access the stack from the top. Assume that initially the stack pointer and the 16-bit register contain 20C016 and 020516 respectively. After the PUSH operation 1. What are the contents of the stack pointer? 2. What are the contents of memory locations 20BE16 and 20BF16?

[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,...

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...
