Compulab CL-SOM-iMX8X SoM & SBC Feature NXP i.MX 8QuadXPlus Quad Core Cortex-A35 Processor

NXP i.MX 8X Cortex-A35 processor designed for automotive infotainment and a variety of industrial applications was officially announced in early 2017 with three parts:

  • i.MX 8QuadXPlus with four Cortex-A35 cores, a Cortex-M4F core, a 4-shader GPU, a multi-format VPU and a HiFi 4 DSP
  • i.MX 8DualXPlus with two Cortex-A35 cores, a Cortex-M4F core, a 4-shader GPU, a multi-format VPU and a HiFi 4 DSP
  • i.MX 8DualX with two Cortex-A35 cores, a Cortex-M4F core, a 2-shader GPU, a multi-format VPU, and a HiFi 4 DSP

In 2018, several companies unveiled i.MX 8X systems-on-module including Toradex Colibri iMX8X and Phytech phyCORE-i.MX 8X, and the processor was launched at the end of that year. There’s now another option with Compulab introducing CL-SOM-iMX8X module powered by NXP i.MX 8QuadXPlus processor, as well as SBC-IMX8X single board computer fitted with the module.
