New | Microprocessor 8085 Ppt By Gaonkar

This article explains who Ramesh Gaonkar is, why his book is the standard reference for the 8085, and how a modern PowerPoint presentation (PPT) based on his "new" or updated materials can be structured for effective learning.

2. Pin Diagram and Demultiplexing (The Tricky Part)

• New PPT Feature: Animated flow of data on the multiplexed AD0-AD7 bus.
• Key Concept: How to use the ALE (Address Latch Enable) signal to separate address from data using an external latch (74373).
• Student Tip: Modern PPTs use colored highlights to show how the same 8 pins serve two purposes.

Gaonkar’s latest curriculum highlights the 8085's hardware efficiency, which simplified computer design by integrating several functions directly onto the silicon. Go to product viewer dialog for this item. microprocessor 8085 ppt by gaonkar new

7. Programming examples (short)

• Move block of memory (simple loop): Use LXI, MOV M,A, INX, DCX, JNZ — demonstrates register indirect and loops.
• Addition of two 8-bit numbers: Load into registers, ADD, check flags, store result.
• BCD adjust (DAA): Use after BCD additions to correct accumulator.

1. Introduction to 8085 Microprocessor: The PPT provides an overview of the 8085 microprocessor, its features, and applications.
2. Architecture of 8085 Microprocessor: The PPT explains the architecture of the 8085 microprocessor, including the ALU, registers, flags, PC, and SP.
3. Instruction Set: The PPT covers the instruction set of the 8085 microprocessor, including arithmetic, logical, and control transfer instructions.
4. Memory Organization: The PPT explains the memory organization of the 8085 microprocessor, including the address bus, data bus, and memory mapping.
5. Interrupts: The PPT covers the interrupt system of the 8085 microprocessor, including the types of interrupts and interrupt handling.

• Hyperlinks: Clickable index linking directly to sections (e.g., "Jump to Timing Diagrams").
• Animated Flowcharts: For sorting algorithms (Bubble sort) written in 8085 assembly.
• Simulator Screencasts: Embedded videos (or links) showing code execution.
• QR Codes: In the corner of slides linking to YouTube tutorials explaining that specific page.
• Updated References: Mentioning modern embedded systems (Arduino, PIC) as descendants of the 8085 architecture.

This 8-bit register indicates the status of the ALU after an operation: S (Sign): Set if the result is negative. Z (Zero): Set if the result is zero. AC (Auxiliary Carry): Used for BCD arithmetic. P (Parity): Set if the number of 1s is even. CY (Carry): Set if an operation generates a carry out. Pin Diagram and Signals This article explains who Ramesh Gaonkar is, why
