Functional safety is an area of computing that is becoming ever more important as we see more and more embedded technologies integrated into our daily lives. Arm’s Automotive Enhanced (AE) line of IP had been launched back in 2018 with the release of the Cortex-A76AE.

Fast-forward a few years, it’s time for a new set of AE IP, with Arm now introducing the new Cortex-A78AE, bringing a higher performance CPU core, and also for the first time introducing an AE class GPU and ISP in the form of the Mali-G78AE and Mali-C71AE. With the move, Arm also says that it is diversifying beyond just the automotive sector and widening the scope to industrial and other autonomous systems.

Hercules-AE is Cortex-A78AE
The new Cortex-A78AE, as its name implies, is based off the Cortex-A78 microarchitecture which we’ve extensively covered in in our in-depth Tech Day article earlier this summer.

Compared to the previous generation Corex-A76AE this means a 30% uplift in IPC and higher performance.
Mali-G78AE - Finally introducing virtualisation
Alongside the Cortex-A78AE, Arm is also for the first time announcing a functional safety capable GPU in the form of the new Mali-G78AE. Based on the mobile Mali-G78 GPU core, we should be expecting similar performance and power efficiency figures from the IP- scaling up from 1 to 24 cores.

The important addition of the new IP is the inclusion of full-fledged hardware virtualisation, a critical feature for autonomous systems that to date had been lacking in the company’s GPU IP.

Beyond the announcement of the new CPU and GPU IP, we’re also seeing an extension of the company’s existing Mali-C71 ISP IP with the new C71AE which adds support for ASIL-B and SIL2 integrity checking.

Also part of the announcement today is Arm’s enablement for reference autonomous platforms: [...]

Arm: Arm Enables Next-Generation Autonomous Systems

Autonomous IP addresses developer needs in deploying next-generation autonomous systems in automotive and industrial applications
We believe that autonomy and autonomous thinking will become the predominant computing workload of the future. Developers deploying Arm autonomous IP stand to enable the flexible, scalable heterogeneous compute required to power next-generation autonomous systems and applications.

Arm Cortex-A78AE is Arm’s highest performance safety capable processor (CPU), delivering 30 percent higher performance than its predecessor at improved power efficiency, and is well suited to automated driving and industrial robotics applications.

Arm Mali-G78AE is Arm’s first safety-capable graphics processor (GPU), including a new Flexible Partitioning feature which allows GPU resources to be allocated to independent hardware partitions to separate autonomous workloads from each other, enhancing safety.

Arm Mali-C71AE is an image signal processor (ISP) that ensures maximum information is extracted from multi-camera autonomous vision systems, which may need to operate in a variety of lighting conditions. Mali-C71AE includes safety features to help achieve ASIL B / SIL 2 level of integrity and address vision applications across automotive and industrial applications.
