CI Results

This repository seeks to provide value to developers targeting ARM platforms. It provides parsers that make code generation and tooling based on SVD easier to build. Most parsers simply parse a provided SVD file and turn it into a data structure more easily used in that language.


ARM provides the following description of CMSIS-SVD (System View Description)

The CMSIS System View Description format(CMSIS-SVD) formalizes the description of the system contained in ARM Cortex-M processor-based microcontrollers, in particular, the memory-mapped registers of peripherals. The detail contained in system view descriptions is comparable to the data in device reference manuals. The information ranges from high-level functional descriptions of a peripheral all the way down to the definition and purpose of an individual bit field in a memory-mapped register.

How Can the CMSIS-SVD Be Used

The generic description of each MCUs CPU and hardware registers is very valuable when generating code that can be used for talking to specific target hardware. In fact, much of the code in parts of CMSIS itself are generated based on the SVD. ARM distributes an executable that does this transformation (SVDConvert.exe).

The information can also be used for building debug tooling, test infrastructure, or whatever else.
