ARM Development Studio 2022.1 Linux

The key new features of this release are:
- Support for Cortex-M85 processor
- Support for other processors previously only provided by the Platinum Edition
- Update of all provided components:
. Arm Compiler for Embedded 6.18
. Streamline Performance Analyzer 8.0

First support for Cortex-M85

Cortex-M85 is the latest processor from Arm for embedded IoT and ML applications. Cortex-M85 is the most capable Cortex-M processor, with micro-architectural improvements to deliver best in class performance, and advanced security features. It is the first processor to implement Armv8.1-M Pointer Authentication and Branch Target Identification (PACBTI-M).

Arm Development Studio 2022.0 provides complete support for Cortex-M85 in all editions. Arm Compiler for Embedded 6.18 allows users to build code optimized for the processor, as well as enabling developers to build code to support PACBTI-M.

An example project highlighting these features is provided, which can be run on the supplied Fixed Virtual Platform and debugged with the Arm Debugger.



Other processors previously only supported in Platinum Edition

This release also makes support available for a number of other Arm processors previously only supported by Platinum Edition. For the first time this includes Armv9-A processors.



Debug and FVP support for these processors requires a license for Silver or higher edition of Development Studio. Compiler support requires a Gold edition or higher license. Example projects are also supplied demonstrating advanced features of these processors, such as SVE2 and bfloat16 support.



These processors are supported by the Streamline Performance Analyzer for Linux, Android, and bare-metal use cases. This Streamline update also adds support for Mali-G510 and Mali-G310 GPUs. Android application developers can also access Streamline for free as part of Arm Mobile Studio.

Arm Development Studiois a professional software development solution for bare-metal embedded systems and Linux-based systems. It covers all stages in development from boot code and kernel porting to application and bare-metal debugging, including performance analysis.


Arm Development Studio IDE
Development Studio helps you build, code, debug and optimize Arm-based projects quickly. From device bring-up to application debug to creating highly efficient micro-controller applications, Development Studio enables you to bring better products to market ahead of the competition.
Arm Compiler
Arm Compiler 5 and Arm Compiler 6 toolchains enable you to build highly optimized embedded applications for the entire range of Arm processors. Arm Compiler 5 supports all Arm architectures from Armv4 to Armv7 inclusive. Arm Compiler 6 supports Armv6-M, Armv7, and Armv8 architectures.
Arm Debugger
Arm Debugger is a graphical debugger supporting software development on Arm processor-based targets and Fixed Virtual Platforms (FVP). The Arm Debugger includes support for SoC bring-up with platform configuration utilities using the Arm ULINK™ and DSTREAM debug probes families.
Arm Fixed Virtual Platforms
Fixed Virtual Platforms (FVPs) provide the ideal combination of performance, flexibility and usability for development and debug at all levels of the software stack. Based on Arm Fast Models, a library of FVPs is supplied with Development Studio for Cortex-A, Cortex-R, Cortex-M and Neoverse processors. In addition, Development Studio supports custom FVPs created using the Arm Fast Models package, via the Platform Configuration Editor (PCE).
Arm Streamline
Arm Streamline is a system-wide performance profiler which can be used to analyze Linux, Android, RTOS and bare-metal embedded systems. Streamline's visualization tools make it easy to identify performance bottlenecks in software running on Arm CPUs, and data-plane workloads running on Arm Mali GPUs and other Arm IP. This is supplemented by a hot-spot software profiler which can identify the dominant functions and call paths in application software, enabling performance tuning of the entire system platform.
Arm Graphics Analyzer
Arm Graphics Analyzer allows you to capture and visualize OpenGL ES, Vulkan and OpenCL API calls made by an application, including capture of application assets and generation of debug visualizations of the application framebuffers. This can be used to identify which API calls are responsible for rendering defects, and makes it easy to identify rendering inefficiencies and performance issues. Arm Graphics Analyzer was formerly known as Mali Graphics Debugger.

Designed specifically for the Arm architecture, Development Studio is the most comprehensive embedded C/C++ dedicated software development solution on the market. Development Studio accelerates software engineering while helping you build robust and efficient products.
