Specifications

Mali-G78AE is the first Arm GPU developed for autonomous use cases to suit both automotive and industrial markets.

Mali-G78AE incorporates a new Flexible Partitioning feature. This feature enables up to four fully independent partitions for true workload separation. Flexible Partitioning allows the allocation of dedicated hardware resources to different workloads, enabling the full separation of safe and non-safe, or time sensitive, workloads. This feature brings the ability to share IP resources across multiple virtual machines (VMs) in a safe and secure manner, which is a key requirement for complex autonomous applications.

Mali-G78AE is part of the Arm Safety Ready portfolio and is developed according to our rigorous functional safety flows and processes. Mali-G78AE is designed to the ISO 26262 and IEC 61508 standards and is safety-capable to ASIL B/SIL 2 diagnostic requirements and ASIL D/SIL 3 for the avoidance of systematic failure. This capability allows deployment for safe human machine interfaces (HMI), and provides the heterogenous compute that is needed in autonomous systems. Arm has worked with ecosystem partner CoreAVI to ensure drivers supporting the latest safety critical APIs are available targeting ASIL D.

Full support for next generation and legacy compute and graphics applications. Including safety critical applications
Bus interface AMBA®5 ACE, ACE-LITE, and AXI Compatible with a wide range of bus interconnect and peripheral IP
L2 cache Configurable 256KB – 4MB
1 to 8 slices
Scalability 1 to 24 cores
Configurable from 1 to 24 cores delivering the largest capability for a Mali GPU
Adaptive Scalable Texture Compression (ASTC) Low Dynamic Range (LDR) and High Dynamic Range (HDR).
Supports both 2D and 3D images.
ASTC offers several advantages over existing texture compression schemes by improving image quality, reducing memory bandwidth and thus energy use
Arm Frame Buffer Compression (AFBC) Version 1.3
4x4 pixel block size
AFBC is a lossless image compression format that provides random access to pixel data to a 4x4 pixel block granularity. It is employed to reduce memory bandwidth both internally within the GPU and externally throughout the SoC
