What term describes the delay between an interrupt request and the start of the corresponding ISR (Interrupt Service Routine)

Interrupt Synchronization

Execution Time

Interrupt Latency

Interrupt Preemption

In Ping-Pong buffering, what is the primary purpose of using two linear buffers that are switched periodically?

To improve the overall storage capacity

To minimize data loss during switching

To simplify the buffering process

To ensure continuous data processing

What is the primary advantage of using a circular buffer vs a linear buffer?

Circular buffer provides faster data access

Circular buffer efficiently manages data streams

Circular buffer prevent data overwriting

Circular buffers have a smaller memory footprint

What was the reason to wait for 12 NOP's instead of 7 encountered in David's case study?

To account for interrupt disable latency

To minimize energy consumption

To synchronize external events

To ensure proper memory allocation

How does circular buffer differ from linear buffer in terms of data organization?

Circular buffer stores data in a sequential order, while linear buffer stores data in a circular fashion

Circular buffer wraps around when reaching the end, while linear buffer shifts data up one position

Circular buffer stores data as linked lists, while linear buffer uses arrays

Circular buffers have a smaller memory footprint than linear buffers

How does the receiver lock on to the incoming data rate?

By advancing or delaying the local clock based on the difference in pointers

By synchronizing the local clock with a dedicated clock signal from the transmitter

By relying on the local clock's crystal oscillator for precise timing

By continuously monitoring and adjusting the local clock's timebase.

Interrupts are always triggered by external events in microcontroller systems.
