New Technologies for the Arm A-Profile Architecturearm Blogs - Nigel Stephens, Lead ISA Architect and Fellow, Architecture and Technology Group, ArmApr. 18, 2019 |
This month, Arm is making available early technical details of two significant new technologies for its A-Profile architecture, both of which are designed to enhance the performance and scalability of parallel software. These new technologies are the Scalable Vector Extension version two (SVE2) and the Transactional Memory Extension (TME).
The purpose of this early disclosure is to inform and enable the OS and tools developer ecosystems, so that support will be widely available by the time CPUs, which deploy these new technologies, become available.
SVE2 allows a wider range of software to benefit from the advanced, scalable SIMD vector technology of the original SVE architecture, announced in 2017. TME allows certain classes of multi-threaded software to be scaled more easily, from running on a few CPU cores to running on many hundreds of cores.
