💡 Hint

Common Mistakes

Confusing bandwidth with latency or power.

The AHB bus supports high bandwidth to allow fast data transfer between components.

2fill in blank

medium

Complete the sentence to describe the APB bus.

ARM Architecture

The APB bus is optimized for [1] speed and low power consumption.

💡 Hint

Common Mistakes

Assuming APB is high speed like AHB.

The APB bus is designed for low speed to save power in simple peripheral communication.

💡 Hint

Common Mistakes

Thinking AHB only supports single transfers.

AHB supports multiple bus masters and burst data transfers for efficiency.

4fill in blank

hard

Fill both blanks to complete the AHB and APB bus roles.

ARM Architecture

AHB is used for [1] data transfer, while APB is used for [2] peripheral communication.

💡 Hint

Common Mistakes

Mixing up which bus is for high or low speed.

AHB handles high-speed data transfer; APB connects simple peripherals at slower speeds.

5fill in blank

hard

Fill all three blanks to complete the dictionary comprehension describing bus features.

ARM Architecture

features = [1]: [2] for [3] in ['AHB', 'APB']

Drag options to blanks, or click blank then click option'

A'bus'

B'high-speed' if bus == 'AHB' else 'low-speed'

Cbus

D'peripheral'

💡 Hint

Common Mistakes

Using string literals instead of variable names for keys.

This comprehension creates a dictionary mapping each bus to its speed characteristic.
