ARM Architecture - Bus Architecture

Why is a bus matrix preferred over a traditional bus in ARM multi-master systems?

AIt allows simultaneous multi-master to multi-slave communication

BIt reduces the number of slaves needed

CIt simplifies the processor design by removing masters

DIt eliminates the need for arbitration

Step-by-Step Solution

Solution:

Step 1: Compare bus matrix and traditional bus
Traditional buses allow only one master at a time, limiting concurrency.
Step 2: Understand bus matrix advantage
Bus matrix supports multiple masters accessing multiple slaves simultaneously, improving performance.
Final Answer:
It allows simultaneous multi-master to multi-slave communication -> Option A
Quick Check:
Bus matrix advantage = Simultaneous multi-master access [OK]

Quick Trick: Bus matrix enables parallel master-slave access [OK]
