Programmable Logic/Programmable Hardware

This page is going to discuss what exactly programmable hardware is.

VLSI
VLSI stands for "Very-Large-Scale Integration", and is the term for a number of different chip architectures that are integrated (many components on a single chip), and are usable for a variety of different purposes. Some more modern chips are referred to as ULSI (U = "Ultra"), but VLSI and ULSI are essentially the same thing.

VLSI (Very Large Scale Integration) refers to integrated circuits with over approximately one hundred thousand transistors. Currently chips with many millions of transistors are sometimes referred to as ULSI (Ultra Large Scale Integration), however the complexity of the designs are approximately the same as VLSI.
