What is an FPGA?

FPGA (Field Programmable + Gate Array)

Semiconductor devices that consist of a regular arrangement of logic gates and programmable interconnects which can be configured (or) reprogrammed to meet the desired application (or) functionality.

Advantages:-

1. Reduced design time
2. Easy later bug fixing
3. Reprogrammable – no waiting for the prototype
4. One FPGA board – multiple configurations
5. Minimal cost

What is a Chip?

Wafer	A disk of Silicon that is cut from the ingots of single-crystal silicon (these are grown from a pot of melted silicon).
Die	Repeated IC's on a wafer.
Chip	Packaged Die (an IC is also called a chip)
