Arm computer-on-module has 1GHz neural processor

Centred on NXP’s iMX93 processor and called VAR-SOM-MX93, the module has a 1GHz NPU (neural processing unit) for AI and machine learning algorithms with 256 MACs (2ops/MAC) which can handle 8bit and 16bit integer RNNs, and 8bit weights.

Alongside this are dual 1.7GHz Cortex-A55 cores, a 250MHz Cortex-M33 for real-time control, up to 2Gbyte of LPDDR4 memory and up to 128Gbyte if eMMC flash.

Display is handled by four lane LVDS (up to 1,366 x 768 or 1,280 x 800) and a parallel interface, and there is a four lane MIPI-DPHY DSI Tx PHY and MIPI-DSI controller.

For cameras there is an ISI camera interface, MIPI-DPHY CSI Rx PHY and MIPI-CSI controller. One processed camera stream at 1080p30 can be handled, or one not-processed (no scaling) camera stream at 4kp30 “depending on system”, said the company.

For industrial communication, it has a CAN-FD interface and dual 1Gbit/s Ethernet controllers, one supporting TSN (time sensitive networking), and the module can be configured to use one of two Wi-Fi modules: One with the NXP IW611 chipset which has 2.4 and 5GHz Wi-Fi and Bluetooth, or another with the IW612 chipset which has 802.15.4 as well.

Minimum recommended power supplied is 3.36V at 2A.

The components on-board are rated for -40 to +85°C although: “customer should consider specific thermal design for the final product based upon
the specific environmental and operational conditions”, according to the company.

Evaluation is supported the the company’s ‘Symphony’ carrier board and there is a Linux board support package.
