Write-Up: Microprocessor 8085 – A Modernized PPT Based on Gaonkar’s New Edition

1. Introduction

The 8085 microprocessor remains a cornerstone in understanding the fundamentals of computer architecture and embedded systems. One of the most authoritative books on this subject is "Microprocessor Architecture, Programming, and Applications with the 8085" by Ramesh S. Gaonkar. The new edition of Gaonkar’s work updates classic concepts with modern pedagogical tools.

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 microprocessor 8085 ppt by gaonkar new
