IMG SERIES4
Beyond next-gen AI
The automotive revolution
Current technology deployed for testing and developing autonomous driving are physically large and very power-hungry, yet they are also underpowered in terms of performance. For large-scale commercial deployment what’s needed is an “edge” solution that offers:
The IMG Series4
IMG Series4 is a ground-breaking neural network accelerator (NNA) for the automotive industry to enable ADAS and autonomous driving. With its incredible high performance at ultra-low latency, architectural efficiency and safety features, it has what is needed for large-scale commercial implementation.
Imagination is working with leading players and innovators in the automotive industry and the multi-core IP has already been licensed. Contact us to start your journey with IMG today.
Multi-core scalability and flexibility
Key to the incredible performance of the IMG Series4 is its multi-core capability. Available in configurations of 2, 4, 6, or 8 cores per cluster, multi-core allows for flexible allocation and synchronisation of workloads across the cores. In combination with Imagination’s software, which provides fine-grained control, multiple workloads can now be executed across any number of cores in the cluster.
Ultra-low latency
Low latency enhances response time, and, on the road, this can be critical to saving lives. By combining the cores in an 8-core cluster, they can all be dedicated to executing a single task, reducing latency, and therefore response time, by a factor of eight.
Incredible performance
Maintaining high levels of utilisation with tera operations per second (TOPS) is a key metric for determining neural network performance. Thanks to its multi-core scalability, IMG Series4 outperforms other solutions on the market by an order of magnitude, with industry-leading performance metrics.
A single IMG Series4 core can deliver up to 12.5 TOPS per core at 1.2GHz in 7nm, and can be arranged in a cluster of 2, 4, 6, or 8 cores, which can be laid down in multiple clusters. An 8-cluster core is 100 TOPS and six of these laid out on a single SoC would therefore deliver 600 TOPS.
Depending on configuration, the IMG Series4 is over 100x faster than using a GPU for AI acceleration and 1000x faster than using a CPU.

Power and bandwidth efficiency
Power efficiency is at the heart of all Imagination designs. The low silicon area IMG Series4 delivers its incredible performance of 12.5 TOPS per core at less than a watt – industry leading performance.
IMG Series4 delivers phenomenal bandwidth efficiency. Processing tensors, the complex 3D maths performed inside a neural network, requires going out to memory and back across the bus. This takes time, consumes memory bandwidth, and absorbs power.
New for IMG Series4 is Imagination Tensor Tiling (ITT) patent-pending technology that solves this problem. It efficiently packages up tensors into blocks, which are then processed in local on-chip memory. This greatly minimises data transfers between layers of the network, reducing bandwidth by up to an incredible 90%.
