Challenge Problems
Push your limits with challenges.
Question 1
Consider a system with a CPU that takes 5 cycles to handle a byte transfer and a DMA that efficiently transfers that byte in 3 cycles. Write an algorithm that demonstrates when it is more beneficial to use DMA over CPU transfers for a 1024-byte data block.
💡 Hint: Calculate both scenarios and compare.
Question 2
Analyze the impact on CPU performance if DMA is integrated into a system that constantly handles high data rates from high-speed peripherals. Include both positive and negative aspects.
💡 Hint: Think about both benefits and challenges of integrating new features into existing systems.
