Challenge Problems
Push your limits with advanced challenges
Suppose you have the Data Segment Register DS = 3000H and an offset of 0070H. Calculate the physical address and explain each step taken.
💡 Hint: Remember, multiplying by 10H is the same as left-shifting the value by 4 bits.
Write and explain an assembly program that demonstrates at least three different addressing modes.
💡 Hint: Include examples of how each mode gains access to data.
