The new suite of IP includes the Arm Cortex-A78AE CPU, Arm Mali-G78AE GPU, and Arm Mali-C71AE ISP. which, according to Am, represent a “step change in compute” for automotive and industrial markets. The three have been engineered to combine with supporting software to enable silicon providers and OEMs to design for self-driving vehicles and industrial machines.
Cortex-A78AE CPU
- Supports features to achieve the relevant automotive and industrial functional safety standards, ISO 26262 and IEC 61508 for applications up to ASIL D / SIL 3
- Enhanced split lock function – in ‘hybrid mode’, which is designed for lower level ASIL requirement application – two or four A78AE cores in split mode, or one or two core pairs in lock mode
- Can match earlier Cortex-A76AE safety CPU performance on 60% lower power (on 7nm)
- 25% greater performance for same power compared with Cortex-A76AE
- 30% Spec2006 (integer and floating-point) compared with Cortex-A76
Mali-G78AE GPU
- Arm’s first GPU to be designed for safety.
- Flexible Partitioning with up to four fully independent partitions for workload separation. “GPU resources can now be utilised for safety-enabled human machine interfaces or for the heterogenous compute needed in autonomous systems,” said the company, giving the example of an infotainment system, an instrument cluster with ASIL B requirements and a driver monitor all running on the same chip, separated by on-chip hardware.
Mali-C71AE
- For autonomous workloads using cameras
- Supports features to achieve ASIL B / SIL2 safety capability.
- Support for four real time cameras or 16 buffered cameras with 1.2Gpixel/s throughput
Chet Babla, vice president of Arm’s automotive and IoT business division, said: “Autonomy has the potential to improve every aspect of our lives, but only if built on a safe and secure computing foundation. As autonomous decision-making becomes more pervasive, Arm has designed a unique suite of technology that prioritizes safety while delivering highly scalable, power efficient compute to enable autonomous decision-making.”
