Embedded Systems Flashcards
Embedded Systems
Embedded System = Special-purpose computer built into a device to perform one specific task.
Key Points to Memorize:
Single task: Does one job (like controlling a microwave or a car engine).
Real-time: Reacts quickly to events.
Small & efficient: Uses limited power, memory, and processing.
Part of something bigger: Not a standalone computer—it’s inside other machines.
“Embedded = Tiny, task-specific computer inside a device, works fast with limited resources, in real time”
Advantages of embedded systems (F.A.S.T.P):
F – Fast performance (real-time response)
A – Affordable (cost-effective for specific tasks)
S – Small size (compact and easy to embed)
T – Targeted (designed for one purpose = efficient)
P – Power-efficient (low power consumption)
Disadvantages of embedded systems (L.I.F.E.):
L – Limited resources (memory, CPU, storage)
I – Inflexible (hard to upgrade or reprogram)
F – Fixed function (not general-purpose)
E – Expensive to design for custom needs (initial development cost)
