Memory Addressing Techniques

This document explores key memory addressing techniques in computer systems: Immediate, Direct, and Indirect Addressing. Immediate Addressing involves storing data in register pairs with specific values, as shown in examples with registers B, C, D, E, H, and L. Direct Addressing assigns data from memory locations directly to registers, illustrated with examples using the accumulator. Indirect Addressing allows the accumulator to load/store information via register pairs, with practical examples provided. Understanding these techniques is essential for efficient memory management in programming.

Presentation Transcript

  1. Memory Addressing Techniques

  2. Immediate Addressing • involves storing data in pairs with immediate values • register pairs:

  3. Immediate Addressing ~ Examples #1 ~ load the B register with 12 and the C register with 34

  4. Immediate Addressing ~ Examples #2 ~ load the D register with 54 and the E register with 32

  5. Immediate Addressing ~ Examples #3 ~ load the H register with 45 and the L register with 67

  6. Direct Addressing • assigns the contents of a memory location to a register • what we have seen so far

  7. Direct Addressing ~ Examples #1 ~ load the accumulator with the contents of address 1234

  8. Direct Addressing ~ Examples #2 ~ store the contents of the accumulator at address ABCD

  9. Indirect Addressing • involves loading and storing information in the accumulator • information in the accumulator is received from register pairs

  10. Indirect Addressing ~ Examples #1 ~ store the contents of registers B and C in the accumulator

  11. Indirect Addressing ~ Examples #2 ~ load the accumulator with FF and store the contents of the accumulator at memory location 2040
