CMSIS DSP : Added a cmake build system
It is not replacing the current MDK and ArmDS projects. It is a complementary way to build CMSIS-DSP. Current version is supporting ARM AC6 compiler from ArmDS. The result of the build can be run on a FVP for instance. It could be extended to use different toolchain and build for different targets. The README.md in DSP folder is giving all the details.pull/19/head

## How to use
|
||||
|
||||
This document is explaining how to use cmake with CMSIS-DSP and AC6 ARM compiler.
|
||||
|
||||
The examples arm_variance_f32 in folder Examples/ARM/arm_variance_f32 has been modified to also
|
||||
support cmake and is used as an example in this document.
|
||||
|
||||
If you don't use AC6, you'll need to modify the cmake files as explained below.
|
||||
|
||||
### Generating the Makefiles
|
||||
|
||||
To build example arm_variance_f32 with cmake, you need to create a build folder where the build will take place. Don't build in your source directory.
|
||||
|
||||
You can create a build folder in Examples/ARM/arm_variance_f32
|
||||
|
||||
Once you are in the build folder, you can use cmake to generate the Makefiles.
|
||||
|
||||
For instance, to build for m7 :
|
||||
cmake -DCMAKE_TOOLCHAIN_FILE=../../../../armcc.cmake -DARM_CPU="cortex-m7" -G "Unix Makefiles" ..
|
||||
|
||||
To build for A5
|
||||
cmake -DCMAKE_TOOLCHAIN_FILE=../../../../armcc.cmake -DARM_CPU="cortex-a5" -G "Unix Makefiles" ..
|
||||
|
||||
To build for A5 with Neon acceleration
|
||||
cmake -DCMAKE_TOOLCHAIN_FILE=../../../../armcc.cmake -DNEON=ON -DARM_CPU="cortex-a5" -G "Unix Makefiles" ..
|
||||
|
||||
cmake will check it can find the cross compiling tools as defined in armcc.cmake
|
||||
|
||||
### Toolchain
|
||||
|
||||
You may have to change the "tools" variable in armcc.make. It is pointing to your toolchain.
|
||||
The version of armcc.cmake on github is using the ARM AC6 compiler coming from the ArmDS environment. The tools variable is thus pointing to ArmDS.
|
||||
|
||||
If you use a different clang toolchain, you can just modify the tools path.
|
||||
|
||||
If you build with gcc, you'll need to change armcc.cmake, config.cmake and configUtils.cmake
|
||||
|
||||
config.make is defining options like -mfpu and the value to pass to gcc (or other compiler) may be different.
|
||||
|
||||
configUtils.cmake is defining the use of a scatter file and it may be different with gcc.
|
||||
|
||||
### Building
|
||||
|
||||
make VERBOSE=1
|
||||
|
||||
### Running
|
||||
|
||||
The executable can run on a FVP.
|
||||
For instance, if you built for m7, you could just do:
|
||||
|
||||
FVP_MPS2_Cortex-M7.exe -a arm_variance_example
|
||||
|
||||
## Customization
|
||||
|
||||
armcc.make is use to cross compil with AC6 coming from ArmDS.
|
||||
|
||||
You'll need to create a different toolchain file if you use something different.
|
||||
Then you'll need to pass this file to cmake on the command line.
|
||||
|
||||
config.cmake is included by the CMSIS-DSP cmake and is defining the options and include paths
|
||||
needed to compile CMSIS-DSP.
|
||||
|
||||
configBoot.cmake are definitions required to run an executable on a platform. It is using files from the Device folder of CMSIS. The result can run on FVP.
|
||||
|
||||
If you need to run on something different, you'll need to modfy configBoot. If you need a different scatter file you'll need to modify configBoot.
|
||||
|
||||
configBoot is relying on some functions defined in configUtils and most of the customizations should be done here.
