The i.MX 8ULP family of processors features NXP’s advanced

implementation of the dual Arm® Cortex®-A35 cores alongside an Arm

Cortex-M33. This combined architecture enables the device to run a rich

operating system (such as Linux) on the Cortex-A35 core and an RTOS

(such as FreeRTOS) on the Cortex-M33 core. It also includes a Fusion

DSP for low-power audio and a HiFi4 DSP for advanced audio and machine

learning applications. The i.MX 8ULP processor provides a 32-bit LPDDR3/

LPDDR4/LPDDR4X memory interface and a number of other interfaces for

connecting peripherals, such as WLAN, Bluetooth™, GPS, and displays.

Additionally, there are 2 co-processors connected to the Cortex-M33 core:

PowerQuad and Casper, accelerating DSP and cryptography functions,

respectively.
