What's included in Development Studio?
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 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 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 and Cortex-M processors. In addition, Development Studio supports custom FVPs created using the Arm Fast Models package, via the Platform Configuration Editor (PCE).
Streamline Performance Analyzer
Arm Streamline Performance Analyzer is a system-wide performance analysis tool to analyse Linux, Android, and bare-metal embedded systems. Streamline's visualization tools make it easy to find performance bottlenecks in CPU, GPU, and other Arm IP. This along with code profiling, enables performance tuning of systems allowing process, thread, function call, and line by line granularity of CPU time to identify inefficient code.
Mali Graphics Debugger
Trace OpenGL ES, Vulkan and OpenCL API calls in applications and understand complex frame effects to identify performance bottlenecks and optimize graphics code. Tracing all API calls in the application makes it easy to pinpoint performance issues and graphics defects. It also gives visibility of application assets including framebuffers, textures, and shaders. Any scene can be re-rendered drawcall by drawcall to see exactly how it is composed, which provides quick detection of graphics defects and issues.
