Answer:
We are provided with three sets of assembly language instructions, and for each set, we need to understand the order in which memory addresses and contents are accessed.
Diagram A:
LDD 106
This instruction means "Load Direct to the accumulator from address 106." The accumulator is a special register in the processor used to hold data for arithmetic or logical operations. In this case, the value stored at memory address 106 (which is 114) will be loaded into the accumulator.
Diagram B:
LDI 104
This instruction means "Load Indirect to the index register from address 104." The index register is another special register in the processor, typically used for memory addressing calculations. Here, the value stored at memory address 104 (which is 100) will be loaded into the index register.
Diagram C:
LDR #3
This instruction means "Load immediate value 3 into the accumulator." Instead of accessing memory, this instruction loads an immediate value (in this case, 3) directly into the accumulator.
LDX 101
This instruction means "Load Direct to the index register from address 101." The value stored at memory address 101 (which is 104) will be loaded into the index register.
To summarize, each diagram represents a different set of assembly language instructions, and the memory addresses and contents accessed are as follows:
Diagram A:
Address 106: Content 114 (loaded into the accumulator)
Diagram B:
Address 104: Content 100 (loaded into the index register)
Diagram C:
No memory address accessed for LDR #3 (immediate value 3 loaded into the accumulator)
Address 101: Content 104 (loaded into the index register)
I hope my explanation has made it easier for you to comprehend these assembly language instructions and the memory accesses they need.
