Dear Forum,

I started coding with CMSIS DSP functions and would like to know whether it is possible to get the functions complied under standard dANSI C without any usage of ARM specific intrinsic or assembler stuff. I would like to run my code on a PC for easier development and reference issues.

Thanks for any hints in advance.

Hi Spachner,

I am not sure if anyone has do this, but from my understanding the End User License Agreement (EULA) limits the distribution and sublicense of the CMSIS DSP library to be used on ARM architecture only.

You can run the compiled library code in instruction set simulators such as the one in Keil MDK. Is there any particular reason for compiling the code on PC?

regards,
Joseph

Note : I am not a lawyer, so my understanding on the EULA might not be accurate :-)

Hi Joseph,

assume you want to develop a algorithm first on a PC for simplicity and reference model reasons. A PC allows to use scripting for automatic test and so on.

Later you have to port your code to the embedded system. When your algorithm needs CMSIS DSP functionally (FFT or whatever) porting would much easier when you can run the same DSP code on PC, too.

Potentially you can use tools like qemu (http://wiki.qemu.org/Main_Page) to emulate the Cortex-M processors.

I think qemu support scripting.

You're welcome.

By the way, you can also get qemu from Linaro
