Arm has announced the latest version of the Armv8-M architecture, known as Armv8.1-M, including the new M-Profile Vector Extension (MVE). The vector extension brings up to 15 times performance uplift to machine learning (ML) functions, and up to 5 times uplift to signal processing functions compared to existing Armv8-M implementations. It may be viewed as the Armv8-M architecture’s version of the Advanced SIMD Extension (Neon) in the A-Profile.
Arm Helium technology is the M-Profile Vector Extension (MVE) for the Arm Cortex-M processor series.
Arm tools are developed along with the architecture. They are now ready for lead partners to start developing software and migrating libraries and other code to Helium, to enable performance increases for DSP and machine learning applications. Tools with support include:
The Armv8.1-M simple programmer’s model, combined with familiar Arm tools, is a key advantage of Helium. Using a single toolchain for control and data processing, leads to lower development costs and less code maintenance.
Arm Fast Models provide fast, flexible programmer's view models of Arm architecture and IP, enabling software development of drivers, firmware, operating systems, and applications prior to silicon availability. Fast Models allow full control over the simulation, including profiling, debug and trace.
There is a Fast Model available for lead partners, which can be used for early software development. It is based on the MPS2 Fixed Virtual Platform (FVP). The Armv8-M architecture envelope model (AEM) has been extended via the plugin interface to support Helium. This provides a suitable platform to get started writing and debugging software.
Development Studio featuring Keil MDK (µVision) has added Helium support for software compilation (Arm Compiler 6) and debugging. This includes disassembly and updated register views for new registers in Armv8.1-M. The toolsuite is also available for lead partners today.
Helium, the M-Profile Vector Extension included in Armv8.1-M, brings significant enhancements to the Cortex-M processor range and will enable the use of a single CPU for both control and data processing code. The performance enhancements enable applications, such as machine learning and DSP.
Arm tools have been developed in parallel with the architecture and are available now for lead partners to start developing software on both Windows and Linux. The Helium support in Arm Compiler 6, combined with leading performance and code density, make it a great choice to get a jumpstart on migrating software to Helium. Arm Fast Models combined with Arm debuggers make it possible to run code and see the Architecture Reference Manual in action.
