The Intel® Quark SoC X1000

The heart of the Galileo is the stylish

on the x86 architecture. The Quark X1000 features:

Up to 400MHz clock speed

16KB L1 Cache

512KB SRAM

Single core, single thread

Integrated SDIO, UART, SPI, USB, I

The Quark X1000's focus is embedded computing – wearable devices, Internet of Things,

autonomous vehicles, or all sorts of other applications. It's intended to be a low-power, x86-based

option for that variety of projects.

Architecture: x86 vs ARM

The Quark X1000 is an x86, which makes it unique in today's single-board computer market. Most

popular SBCs – including the

ARM-based processors. x86 processors are usually used in desktop computers, running Windows

or OS X, because they're faster and more powerful. ARM processors, on the other hand, are more

often used in portable electronics because they're more power-efficient.

ARM and x86 differ at fundamentally philosophical level: the size of their instruction set. ARM is a

RISC (Reduced Instruction Set Computing, a smaller, simpler instruction set) architecture and x86

processors are CISC (Complex Instruction Set Computing, a more complex, and powerful set).

Something that takes an x86 one clock cycle, might take an ARM processor three. A large

instruction set requires more hardware, which requires more power to run.

Intel's Atom and Quark products try to combat the high power consumption. They're directed at the

mobile market. But they're still x86 architectures, and they'll still consume more power.

Software Download/Setup

On this, and the next few pages, we'll overview the steps that you'll need to follow in order to upload

Arduino code to the Galileo. As usual, it all starts with downloading software. Unfortunately, the

Galileo won't work with the standard Arduino IDE (integrated development environment), so we'll

have to download and install a specialized version.

Download the Arduino IDE for Galileo

The Arduino Galileo is so wildly different from any other Arduino platform – it's x86-based, and most

commands are sent via the Linux terminal. As such, an entirely re-purposed version of the software

is required to upload an Arduino sketch to the board. Click the link below to download the Galileo-
