Intel Launches 10nm Atom Embedded CPUs: Elkhart Lake Now Available [anandtech.com]

The embedded and edge markets for Intel have always been hidden away within its IoT business, however at the Investor Meeting last year it was highlighted as one of Intel's key growth areas. The requirements for businesses to enable automation and control, as well as apply machine learning or computer vision, have increased as new optimized algorithms and use cases enter the market, and this is the question that the new 10nm Atom Embedded CPUs are set to answer.

The new processors built with Tremont Atom cores will come as three series of processors: Pentium, Celeron, and Atom x6000E. These are all built with the same silicon die, offering up to four Atom cores with a 3.0 GHz turbo frequency, up to 850 MHz of Gen11 graphics (up to 32 EUs, three 4K60 displays), in TDPs ranging from 4.5 W to 12 W. All processors will support up to LPDDR4X-4267 or DDR4-3200. In-band ECC support is split - the Atom x6000E parts have it, but the Pentium and Celerons do not.

Some of the lineup will include [linuxgizmos.com] a single ARM Cortex-M7 [wikipedia.org] companion core:

According to Intel, the Atom x6000E family is its first product line to specifically target Internet of Things applications. This is not entirely true, considering that Atom SoCs such as Bay Trail E3800 and Apollo Lake E3900 have targeted IoT duty since the IoT term was invented. IoT was also the main focus of Intel's discontinued line of super low-power Quark [linuxgizmos.com] processors.

Nevertheless, Intel has added a host of embedded-focused features starting with an Intel Programmable Services Engine (Intel PSE) built around a real-time Arm Cortex-M7 companion core. Intel PSE hosts new functions like remote, network proxy, embedded controller, and sensor hub. The Cortex-M7 is designed to run the open source, Intel-derived Zephyr [linuxgizmos.com] RTOS.
