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.
