Intel Quark
Intel Quark is a line of
32-bit x86 SoCs and microcontrollers 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, and discontinued in January 2019.[1]
Quark processors, while slower than

i586) CPU.[6]
History
The first product in the Quark line is the single-core
SDIO, power management controller, and GPIO. There are 16 kB of on-chip embedded SRAM and an integrated DDR3 memory controller.[7][8]
A second Intel product that includes Quark core, the
In January 2015, Intel announced the

unit and a battery charge controller.
Intel announced the end-of-life of its Quark products in January 2019, with orders accepted until July 2019 and final shipments set for July 2022.[1][11]

Segfault bug
Intel Quark SoC X1000 contains a bug (#71538)[17] that "under specific circumstances" results in a type of crash known as a segfault. The workaround implemented by Intel is to omit LOCK prefixes (not required on single-threaded processors) in the compiled code.[18] While source-based embedded systems like those built using the Yocto Project can incorporate this workaround at compile time, general purpose Linux distributions such as Debian are deeply affected by the bug. Such a workaround is not easy to implement in binaries meant to support multithreading too as they require LOCK prefixes to function properly.[19]
