The fundamental first machine cycle of every instruction, usually requiring 4 T-states ( ) to retrieve the instruction byte from memory. Slide 8: The 8085 Instruction Set and Addressing Modes Slide Title: Addressing Modes and Instruction Groups Core Concepts:
An 8-bit register that is part of the Arithmetic Logic Unit (ALU). It holds one of the operands for arithmetic/logical operations and stores the final result.
The presentation typically spans over 300 slides, covering everything from basic binary concepts to advanced peripheral interfacing. Structured Learning: It is often organized into a 5-week curriculum: Basic concepts of microprocessors vs. microcomputers. Detailed internal architecture of the 8085. Addressing modes and the 74-instruction set. Interrupt structures (TRAP, RST 7.5, etc.). microprocessor 8085 ppt by gaonkar
Strengths
B, C, D, E, H, and L (8-bit each; can be used as 16-bit pairs). Program Counter (PC): The fundamental first machine cycle of every instruction,
When assembling a PowerPoint presentation based on this material, remember that Gaonkar’s instructional strength lies in clarity and logical progression. Begin with the internal block diagram, transition to individual pin configurations, explain how instructions utilize those pins via timing diagrams, and conclude with programming or interfacing examples. This logical flow ensures that students grasp both the abstract architecture and its practical execution.
The 8085 communicates with memory and I/O using its 16-bit address bus and 8-bit data bus. Using memory mapping ( ), the 8085 can address 64 KB of memory (RAM/ROM). The presentation typically spans over 300 slides, covering
Uses an 8-bit independent address space isolated from memory. Uses dedicated IN and OUT instructions to communicate over 256 unique I/O ports.
The primary 8-bit register used to store data during ALU operations and receive the final result.
