The UDOO X86 contains an embedded Intel Arduino 101, powered by Intel's Curie™ module comprising of two cores operating simultaneously.
- The Intel® Quark SE™ Core, a 32 MHz x86 processor, compatible with the Pentium x86 instruction set. Manages the USB interface (routed internally on the UDOO X86), and Bluetooth Low Energy. Contains 384 kB of on-die flash & 80 kB of on-die SRAM.
- The ARC, a 32 MHz Argonaut RISC Core. This is where compiled Arduino Sketches are executed. The ARC can communicate directly with the six-axis accelerometer/gyroscope. The memory subsystem is shared with the Quark SE™, which also manages the communication between the two cores.
