OAX8000 is an automotive ASIC optimized for dedicated DMS (Driver Monitoring Systems). The ASIC comes with a stacked-die architecture with multiple layers of ICs that offers on-chip DDR3 SDRAM memory (1GB). It also features a fast AI video processor with CNN (Convolutional Neural Network) accelerator and works as a low-power device. The automotive image sensors have a power rating of 1 watt.
The AI-enabled OAX8000 ASIC integrates an NPU and ISP (Image Signal Processor), which performs up to 1.1 TOPS for eye gaze and eye tracking algorithms. This integration also reduces the board area for the ECU (Engine Control Unit) by optimization of DMS systems. OAX8000 ASIC has a quick boot-up time that minimizes the delay between ignition and activation of the DMS camera. It also comes with secured boot functionalities for cybersecurity.

OAX8000 ASIC has a built-in NPU that has flexible support of almost all deep learning frameworks and tools like TensorFlow, Caffe, MXNet, and ONNX. It also integrates quad Arm Cortex A5 CPU cores with Neon technology for enhanced video encoding and decoding with advanced video analytics algorithms. It also comes with hardware for image processing and RGB/IR processing.
The ASIC has a flexible input processing capacity that allows the sensing of widely contrasting bright and dark images, due to its HDR processing feature. Hence, the applications are dynamic that can function in the day as well as at night. The embedded video encoder allows up to 5 megapixels of captured data from automotive image sensors and outputs up to 2K resolution video at 30 frames per second.
