8085 Microprocessor: Flags, Memory, Pipelining, and DMA

What is a Flag Register? 8085 Flags Explained

The Flag Register in the 8085 microprocessor is an 8-bit register reflecting the outcome of arithmetic and logical operations. It contains 5 main flags, each occupying one bit, indicating conditions arising during instruction execution. These flags help the microprocessor make decisions and control operations based on specific conditions.

The 8085 microprocessor has five flags:

1. Zero Flag (Z): Set when the result of an arithmetic or logical operation

VTP and Spanning Tree Protocol (STP) for Network Management

VLAN Trunking Protocol (VTP)

VTP allows a network administrator to propagate VLAN configurations across a network.

Benefits of VTP

  • Consistency in VLAN configuration.
  • Accurate VLAN tracking and monitoring.
  • Dynamic reports on added VLANs.
  • Dynamic trunk configuration.

VTP automatically synchronizes domain and VLAN configurations. Use show vtp status to display network status and recommended actions.

VTP Modes

  • Server: Create, modify, and delete VLANs (default mode).
  • Client: Receives and applies VTP information

DHCP Protocol

Introduction

DHCP (Dynamic Host Configuration Protocol) is a TCP/IP layer application. It’s a standard designed to simplify IP address management on a network.

This protocol uses a client/server model, enabling centralized network management. A server maintains a pool of dynamic IP addresses.

The server assigns IP addresses to connecting clients, providing necessary configuration information without prior network knowledge.

The server logs IP address usage, tracking which addresses are in use and for

Encoders and Flip-Flops in Digital Circuits

What is an Encoder? Designing an 8:3 Encoder

An encoder is a combinational circuit that converts an active input signal into a corresponding binary output code. It performs the opposite function of a decoder. Encoders take multiple input signals and encode them into fewer output bits. The number of output bits depends on the number of input lines.

For instance, an n-to-m encoder takes n inputs and generates an m-bit binary code as output, where m is the number of bits required to represent the number
