Complete the sentence to describe the primary function of a bus matrix in ARM architecture.
A bus matrix in ARM architecture primarily [1] multiple masters to access shared resources efficiently.
The bus matrix connects multiple masters, such as CPUs and DMA controllers, allowing them to access shared resources like memory or peripherals efficiently.
Complete the sentence to explain how a bus matrix handles simultaneous requests.
When multiple masters request access at the same time, the bus matrix [1] these requests to avoid conflicts.The bus matrix arbitrates between simultaneous requests, deciding which master gets access first to prevent conflicts and ensure smooth operation.
Fix the error in the statement about bus matrix ports.
Each master in a bus matrix connects to a dedicated [1] port to communicate with slaves.
Each master connects to a dedicated master port on the bus matrix, which then routes requests to slave ports connected to peripherals or memory.
Fill both blanks to complete the description of bus matrix arbitration.
The bus matrix uses a [1] scheme to decide access priority, ensuring [2] between masters.
The bus matrix often uses a round-robin arbitration scheme to ensure fairness, giving each master a chance to access the bus in turn.
Fill all three blanks to complete the explanation of bus matrix benefits.
A bus matrix improves system performance by [1] bandwidth, [2] latency, and [3] simultaneous access.
The bus matrix increases bandwidth, reduces latency, and allows simultaneous access by multiple masters, improving overall system efficiency.
