## Question

Define throughput of a system.

## Short answer

Throughput is the number of tasks or amount of data processed per unit time (e.g., bits/second). It measures work completed, distinct from latency; pipelining can increase throughput without reducing single-task latency.

## Answer

**Throughput** is the number of tasks (or amount of data) a system can process per unit time, e.g. frames per second or bits per second. It measures how much work the system completes in a given period.

It differs from *latency* (the time to finish one task). Pipelining or parallelism can raise throughput without reducing the latency of a single task. For a system whose one task takes t seconds and that cannot overlap tasks, throughput = 1/t; with overlapping stages, throughput can be higher than 1/t.

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. Throughput of a system is:
   A. Time to finish one task
   B. Power consumed
   C. Number of tasks or amount of data processed per unit time
   D. Memory size
   Answer: C. Throughput measures work completed per unit time, e.g. frames/s or bits/s. (Key point: Throughput definition)

2. How does latency differ from throughput?
   A. Latency is cost
   B. They are the same
   C. Latency is tasks per second
   D. Latency is time for one task; throughput is tasks per unit time
   Answer: D. Latency is the time for one task. (Key point: Latency vs throughput)

3. What can pipelining do?
   A. Raise throughput without reducing single-task latency
   B. Reduce throughput
   C. Reduce all latencies to zero
   D. Remove tasks
   Answer: A. Overlapping stages processes more tasks per second though each still takes the same time. (Key point: Pipelining effect)
