Release Notes for Arm Development Studio 2021.0 - Released March 23, 2021

Arm Compiler
- Updated Arm Compiler 6 to 6.16 for the latest features, bug fixes and performance improvements. The complete release notes are available on the Arm Compiler 6 Downloads page.
Note:Arm Compiler 5.06 update 7 is the final planned maintenance update to Arm Compiler 5.06. With this release, Arm Compiler 5 becomes a legacy product and has reached the end of Mainstream Support.
Arm Compiler 5 is a proven and mature toolchain for the Arm targets that it supports. It can still be used for:
- Existing projects.
- New projects for legacy Armv4, Armv5, or Armv6 targets.
For all other new projects, Arm strongly recommends that you upgrade to the latest release of Arm Compiler 6 (or later).
From the next Arm DS release, Arm Compiler 5 will be not included in the installation package. However, Arm Compiler 5 can be still downloaded independently from

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.
