The NXP i.MX 937 quad-core Cortex-A55 microprocessor (MPU) is designed for HMI and Edge AI applications, bridging the gap between entry-level NXP i.MX 93 SoCs and higher-end models like the NXP i.MX 952 processor family, with pin-to-pin compatibility with the latter.
The i.MX 937 MPU incorporates a 667 MHz Arm Cortex-M7 for real-time tasks, a low-power Arm Cortex-M33 core for system management, supports LPDDR4x or LPDDR5 memory, and includes an Arm Mali G310 3D GPU, a VPU for 1080p H.26x video encoding and decoding, and a 2 eTOPS NXP eIQ Neutron NPU for machine learning (ML) acceleration. For HMI applications, it features MIPI DSI and LVDS display interfaces, a 4-lane MIPI CSI camera interface, and various other I/Os.
