Intel Quark

Intel Galileo-Board with Quark-Processor

Intel Quark is a line of 32-bit x86 SoCs by Intel, designed for small size and low power consumption, and targeted at new markets including wearable devices. The line was introduced at Intel Developer Forum in 2013. They are smaller and slower than Atom processors and consume less power. They lack support for SIMD instruction sets (such as MMX and SSE)[1] and only support embedded operating systems. Quark powers the Intel Galileo developer microcontroller board.[2] The CPU instruction set is the same as a Pentium (P54C/i586) CPU[3]

The first product in the Quark line is the single-core 32 nm X1000 SoC with a clock rate of up to 400 MHz. The system includes several interfaces, including PCIe, UART, I2C, Fast Ethernet, USB 2.0, SDIO, PMC, and GPIO. There are 16 kilobytes of on-chip embedded SRAM and an integrated DDR3 memory controller.[4][5]

A second Intel product based on Quark, the Intel Edison microcomputer, was presented in January 2014. It has a form factor close to the size of an SD card, and is capable of wireless networking using Wi-Fi or Bluetooth.[6]

In January 2015, Intel announced the sub-miniature Intel Curie module for wearable applications, based on a Quark SE core with 80 KB SRAM and 384 KB flash.[7] At the size of a button, it also features a 6-axis accellerometer, a DSP sensor hub, an Bluetooth LE unit and a battery charge controller.

Segfault bug

Intel Quark SoC X1000 contains a bug #71538[8] that "under specific circumstances" results in crash (segfault). The workaround Intel implemented in supported Yocto Linux is to prepend the affected LOCK instruction in the compiled code with a NOP instruction.[8] General purpose Linux distributions such as Debian are affected by the bug and the fix is not easy to implement as multithreading systems require LOCK instruction to function properly.[9]
