What is the purpose of the Register Indirect Mode?
Think about how operating systems use registers.
Can you name one advantage of using register indirect mode over direct mode?
Consider execution time and efficiency.
What does Register Indirect Mode use to access operands?
Think about how we can use a register to reference another place.
Is Register Indirect Mode more efficient than Memory Indirect Mode?
Consider the number of steps involved in each mode.
Design a program that uses register indirect addressing to create a dynamic array where the size is determined at runtime. Explain the steps taken in your program.
Consider how dynamically sized structures affect memory allocation strategies.
Compare the execution time of using direct versus register indirect addressing in a mini-case study. What results do you expect?
Think about memory accesses and computational time per operation.
