Its datasheet is not a single, public document but is instead a comprehensive collection of technical specifications, application notes, and design guidelines. This article synthesizes all the available technical information to create a complete reference for engineers, developers, and technology analysts.
Powering lane-keeping, adaptive cruise control, and pedestrian avoidance.
: A dedicated deep-learning neural network engine designed to parse visual fields simultaneously for object classification, pixel segmentations, and structural depth estimations. Silicon Processing and Packaging Specifications
Designed from the ground up to meet ASIL (Automotive Safety Integrity Level) standards. Hardware failure detection mechanisms, such as error-correcting code (ECC) on all internal memories and registers, catch potential data corruption. eyeq4 datasheet
: Six specialized VLIW/SIMD programmable vector engines. These handle high-density, short-integral data calculations foundational to raw computer vision and pixel manipulation.
: Capable of 2.5 Teraflops (TFLOPS) of performance. It is approximately 10 times more powerful than the EyeQ3.
