This is the block diagram for MDK-Professional components.  

MDK-Core

Based on the µVision® IDE, it combines project and run-time environment management, as well as build facilities with source code editing and program debugging in a single environment.

It provides leading support for Arm Cortex-M based devices, including the Armv8-M architecture (Cortex-M23/M33/M35P).

C/C++ Compiler

Built to generate optimum code size and best-in-class performance, Keil MDK includes the leading Arm C/C++ Compiler. It includes assembler, linker and highly optimized run-time libraries to ensure optimal performance.

Arm Compiler 6 is qualified for functional safety applications by TÜV SÜD for various safety standards.

Debug

Test, verify and optimize application code in a single environment.

MDK offers run/stop debugging, the use of data trace, and even non-intrusive instruction trace to facilitate debug and system optimization. Using a ULINK debug probe , features like streaming trace and power measurement become available.

Software Packs

MDK uses software packs for device and board support, CMSIS libraries, middleware, code templates, as well as example projects.

They may be added any time to MDK-Core which makes support for new devices and middleware updates independent from the toolchain. Pack Installer manages the list of available packs.
