easy📝 Conceptual Q2 of 15
Step-by-Step Solution
Solution:
Step 1: Identify the role of arbitration in bus matrix
When multiple masters request access to the same slave, a decision is needed to avoid conflicts.Step 2: Recognize the arbiter's function
The arbiter manages access priority and grants permission to one master at a time.Final Answer:
Arbiter -> Option AQuick Check:
Access control = Arbiter [OK]
Quick Trick: Arbiter controls access when masters compete [OK]
Common Mistakes:
- Confusing arbiter with decoder
- Thinking multiplexer manages access priority
- Assuming registers decide access
