CMSIS Cortex Microcontoller Software Interface Standard compliant
MDK-ARM is available in four editions: MDK-Lite, MDK-Basic, MDK-Standard, and MDK-Professional. All editions provide a complete C/C++ development environment and MDK-Professional includes extensive middleware libraries. Refer to the Product Selector for more details.
The Keil RTX is a royalty-free, deterministic Real-Time Operating System designed for ARM and Cortex-M devices. It allows you to create programs that simultaneously perform multiple functions and helps to create applications which are better structured and more easily maintained.
Features
Royalty-free, deterministic RTOS with source code
Flexible Scheduling: round-robin, pre-emptive, and collaborative
High-Speed real-time operation with low interrupt latency
Small footprint for resource constrained systems
Unlimited number of tasks each with 254 priority levels
Unlimited number of mailboxes, semaphores, mutex, and timers
Support for multithreading and thread-safe operation
Kernel aware debug support in MDK-ARM
Dialog-based setup using µVision Configuration Wizard
Benefits
While it is certainly possible to create real-time programs without an RTOS (by executing one or more functions in a Super-loop), there are numerous scheduling, maintenance, and timing issues that an RTOS like the Keil RTX solves for you. For a more detailed comparison between RTOS and Super-loop, take a look at the advantages of using an RTOS.
MDK-ARM Devolepment Tools
The Keil MDK-ARM Microcontroller Kit is a complete software development environment for the wide range of ARM, Cortex-M, and Cortex-R based microcontroller devices. MDK includes the uVision IDE/Debugger, ARM C/C++ Compiler, and essential middleware components. It's easy to learn and use. The MDK-ARM is a complete software development environment for Cortex™-M, Cortex-R4, ARM7™ and ARM9™ processor-based devices.

Hardware and Software Limitations
Keil development development tools without a current product license run as a Lite/Evaluation edition and have the following restrictions:
MDK-ARM Lite Edition
Programs that generate more than 32 Kbytes of code and data will not compile, assemble, or link.
The debugger supports programs that are 32 Kbytes or smaller.
The compiler does not generate a disassembly listing of the machine code generated. The -S, --asm, and --interleave compiler command-line options are disabled. Projects will not compile with Target -> Listing -> C Compiler Listing enabled.
The compiler and assembler do not generate position-independent code or data. The --apcs /ropi /rwpi /pic/ pid compiler and assembler command line options are disabled.
The assembler and linker create Symbolic Output Format objects which cannot be linked with third-party linker utilities. Fully licensed tools generate standard ELF/DWARF files which may be used with third-party utilities.
The linker does not accept scatter-loading description files for sophisticated memory layouts. The --scatter command line option is disabled.
C51 Evaluation Tools

Programs that generate more than 2 Kbytes of object code will not compile, assemble, or link.
The debugger supports programs that are 2 Kbytes or smaller.
The startup code generated includes LJMPs. Code generated cannot be used in single-chip devices that support 2 Kbytes or less of program space.
Programs start at offset 0x0800. Programs generated with the evaluation software may not be programmed into single-chip devices with less than 2 Kbytes of on-chip ROM.
