IMG 4NX-MC4
neural network acceleration
Key Features
Ultra-low latency
Low latency improves response time, which can be critical for saving lives on the road. When multiple cores are combined, they can all be dedicated to executing a single task, reducing latency and thus response time by a factor of eight.
Leading safety mechanisms
IMG Series4 incorporates IP-level safety features and is built using a design process that assists customers in achieving ISO 26262 certification. This enables functionally-safe neural network inference without compromising performance.
Stellar bandwidth efficiency
Imagination Tensor Tiling (ITT) efficiently packages up tensors into tiles, which are then processed in groups for which all the intermediate data is stored in local on-chip memory, minimising data transfers between layers of the network.
Multi-core flexibility
Multi-core allows for flexible allocation and synchronisation of workloads across the cores. Imagination’s software, which provides fine-grained control and increases flexibility through batching, can now be exploited across any number of cores.
Data Centre
Graphics-rich applications such as cloud based gaming or content creation on data centre services where cost management is key.
Entry level ADAS
Vehicles targeting L1 “feet free” style ADAS workloads, such as Cruise Control.
Premium ADAS
Vehicles targeting L2+ “hands free” and beyond ADAS features and flexible coverage of both graphics and compute tasks.
