Developments in the Arm A-Profile Architecture: Armv8.6-A

The Arm Architecture is continually evolving to meet the needs of our ecosystem partners. This blog gives a high-level overview of some of the changes being introduced in Armv8.6-A.

The enhancements to the architecture provide more efficient processing and better enable new areas such as Neural Networks (NN) for Machine Learning (ML). Both General Matrix Multiply (GEMM) and BFloat 16 provide major improvements in this area. We introduce further security features with enhancements to pointer authentication support.

Full Instruction Set and System Register information will be available via our technical webpages. The complete Armv8-A Architecture Reference Manual (ArmARM), documenting Armv8.6-A and earlier functionality, is due for release next year. XML releases will be available soon and we will link to those when available.

Details of previous updates to the A-Profile architecture are available here: Armv8.1-A, Armv8.2-A, Armv8.3-A,  Armv8.4-A, and Armv8.5-A.
