Microprocessor 8085 Ppt By Gaonkar New

The Definitive Guide to the Microprocessor 8085: Unlocking the "Gaonkar New" PPT Experience

Part 6: Case Study – A Perfect Slide from a "New Gaonkar PPT"

Imagine you find a deck titled Gaonkar_8085_Unit4_Interrupts_v2024.pptx. Let’s review what an exemplary slide looks like.

Slide Title: Hardware Interrupts in 8085 microprocessor 8085 ppt by gaonkar new

Content Layout:

  • Top Right (Diagram): A vector graphic showing the 8085 pins (TRAP, RST 7.5, RST 6.5, RST 5.5, INTR) entering the interrupt control logic.
  • Left Column (Text):
    • TRAP: Non-maskable, Edge & Level sensitive (Highest Priority).
    • RST 7.5: Maskable, Rising Edge, Restart address 003CH.
    • RST 6.5: Maskable, Level sensitive, Restart 0034H.
  • Bottom (Animation box): "Click to show difference between Vectored vs Non-vectored."
    • Pop-up text: "INTR is Non-vectored (requires external hardware to supply opcode). All others are Vectored."
  • Footer: Source: Gaonkar, Ch. 12 (Updated for 2023 syllabus).

This structure is information-dense but visually clear—the hallmark of a modernized educational slide. The Definitive Guide to the Microprocessor 8085: Unlocking

Slide 5: Pin Diagram & Signals (New annotated version)

  • Multiplexed AD0–AD7, A8–A15.
  • Control signals: RD, WR, ALE, IO/M, S0, S1.
  • New addition: simplified signal grouping table.

Slide 14: 8085 vs Modern Microcontrollers (New slide)

  • 8085 → 8051 → Arduino (AVR) → STM32.
  • What remains relevant: registers, flags, interrupts, stack.

7. Interrupts in the 8085

  • The Hierarchy: TRAP (Highest), RST 7.5, RST 6.5, RST 5.5, and INTR (Lowest).
  • New Visuals: A vector table showing memory locations (e.g., RST 5.5 calls 002CH).
  • Masking: Explanation of the SIM (Set Interrupt Mask) and RIM (Read Interrupt Mask) instructions—a topic often butchered in older PPTs.

10. Solved Problems and Objective Questions (Exam Focus)

  • The "New" Advantage: Inclusion of MCQs (Multiple Choice Questions) matching the GATE and technical university exams.
  • Case Studies: Traffic light controller or washing machine controller using the 8085.

6. Stack and Subroutines (The RST Concept)

  • New PPT Feature: Comparison of CALL vs JMP; using PUSH and POP to preserve register status.
  • Gaonkar’s Value: Clear explanation of the Stack Pointer (SP) initialization and how it decrements during pushes.

Slide 6: Addressing Modes (With Program Snippets)

  • Immediate, Register, Direct, Indirect, Implied.
  • New PPT style: Each mode appears as a card with a small example.
    • Immediate: MVI A, 05H
    • Indirect: MOV A, M (M points to HL pair)
  • Interactive element (in PPT): Click to reveal the machine code (opcode + operand bytes).
