ARM Architecture - Bus Architecture

In a complex ARM system, how does the bridge between AHB and APB buses manage data transfer?

AIt disables APB when AHB is active

BIt speeds up APB transactions to match AHB speed

CIt converts high-speed AHB transactions to simpler APB transactions

DIt merges APB and AHB buses into one unified bus

Step-by-Step Solution

Solution:

Step 1: Understand bridge function
The bridge adapts AHB's complex, high-speed transactions to APB's simpler protocol.
Step 2: Analyze options
Bridge does not speed up APB or merge buses; it translates transactions for compatibility.
Final Answer:
It converts high-speed AHB transactions to simpler APB transactions -> Option C
Quick Check:
Bridge translates AHB to APB protocol [OK]

Quick Trick: Bridge adapts AHB to APB protocol [OK]
