## Question

How does a FPGA differ from a microcontroller?

## Short answer

An FPGA configures its internal hardware logic blocks and interconnects to implement circuits directly, enabling true parallel operation. A microcontroller has a fixed CPU that executes program instructions sequentially.

## Answer

An FPGA is a programmable array of logic blocks and interconnect whose hardware is configured to implement the circuit itself, so many operations run truly in parallel. A microcontroller is a fixed processor (CPU with memory and peripherals on one chip) that executes a program instruction by instruction in sequence.

## Check yourself

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

1. What does an FPGA consist of?
   A. A fixed CPU with memory
   B. A programmable array of logic blocks and interconnect configured to implement the circuit
   C. Only a timer
   D. A single ALU
   Answer: B. An FPGA's hardware is configured to be the circuit itself. (Key point: FPGA hardware)

2. Why can an FPGA do many operations at once?
   A. It has a faster clock always
   B. It executes instructions in sequence
   C. The configured hardware runs truly in parallel
   D. It has many CPUs
   Answer: C. Different parts of the configured logic operate simultaneously. (Key point: Parallelism)

3. How does a microcontroller execute its program?
   A. By reconfiguring logic
   B. All lines in parallel
   C. Using no memory
   D. Instruction by instruction in sequence
   Answer: D. It is a fixed processor that runs a program step by step. (Key point: Microcontroller execution)
