Difference between CMSIS-RTOS-v1 and RTX?

SP Lee

Hi,

I am a begineer, and I would like to understand what are the differences between CMSIS-RTOS-v1, and RTX?

Is RTX a product of Keil?

Thank you

    CMSIS-RTOS-v1 is the name of a RTOS standard. It defines APIs and specifications etc. Keil RTX v4.x is an implementation of the standard CMSIS-RTOS-v1 with source code and libraries for users to work with in their projects.

    Since CMSIS-RTOS-v1 and CMSIS-RTOS-v2 are open source projects, users or third parties can implement their own RTX based on these two RTOS API standards.
