Advanced Assembly Programming with Bitwise and Conditional Instructions

Objective: Dive deeper into assembly language programming by tackling scenarios that necessitate the use of bitwise operations and conditional branching, enriching understanding of practical instruction set applications.

Extended Instruction Set:

AND Rx$,$ Ry$,$ Rz: Executes a bitwise AND between the values in Ry and Rz$,$ storing the outcome in Rx$.$

OR Rx$,$ Ry$,$ Rz: Executes a bitwise OR between the values in Ry and Rz$,$ storing the outcome in Rx$.$

BNE Label: Branches to a specific label if the preceding comparison did not result in equality.

CMP Rx$,$ Ry: Compares the values in Rx and Ry$,$ preparing the stage for conditional branching based on the comparison's outcome.

Memory Table for Context:

Address Value

$5008$

$5014$

$5022$

$60015$

$60110$

Tasks:

a$.$ Develop pseudo$-$instructions to perform a bitwise AND operation on the values at memory locations $500$ and $501,$ and a bitwise OR operation on the values at $500$ and $502.$ Then, store the AND result in $503$ and the OR result in $504.$

b$.$ Construct pseudo$-$instructions to compare the values at memory locations $600$ and $601.$ If $600$ is greater, store $1$ in $602$; otherwise, store $0$ in $602.$
