A comprehensive, modernized exposition of the Intel 8085 microprocessor inspired by Gaonkar’s clear pedagogical style—covering architecture, timing, instruction set, interfacing, system design examples, and hands-on labs—aimed at undergraduate computer engineering courses and embedded-systems practitioners who wish to understand legacy 8-bit microprocessors and their design principles.
Gaonkar categorizes the 8085 instructions into five functional groups: Data Transfer, Arithmetic, Logical, Branching, and Machine Control. These instructions interact with memory through five Addressing Modes Immediate: Data is part of the instruction (e.g., MVI A, 40H Data is stored in registers (e.g., The memory address is specified in the instruction. A register pair (like H-L) holds the memory address. The operand is hidden within the opcode (e.g., for complement accumulator). Conclusion microprocessor 8085 ppt by gaonkar
Most students focus on parallel data transfer, but Gaonkar highlights a unique feature of the 8085: built-in serial communication. A comprehensive, modernized exposition of the Intel 8085
If you are studying for an exam, do not just download any random PPT. Ensure that the slides reference Gaonkar’s specific examples—especially his 8255 PPI interfacing problems. Whether you find a ready-made deck or build one yourself using his textbook as a blueprint, mastering the 8085 through Gaonkar’s lens guarantees a strong foundation in embedded systems. A register pair (like H-L) holds the memory address
