OMAP L138 with C6RunLib: Modifying Function Signatures For Cache Optimizations

Alexander Kiermayer

Hi,

i read in the C6RunLib Wiki that the direction of buffers passed to a C-function can be indicated with the keywords INBUF, OUTBUF, INOUTBUF, NONE.

You can find the text here: http://processors.wiki.ti.com/index.php/C6RunLib_Documentation#Modifying_Function_Signatures_For_Cache_Optimizations

Can anyone tell me, which header i have to include?

If i just put the keywords in my code i got the following error:

"error: expected declaration specifiers or '...' before 'OUTBUF' "

Thanks you guys,

Alex

Alex,

What version of C6Run are you using? I think in the older releases you would need to make dummy defines in the source, like the following:

#define INBUF
#define OUTBUF
#define INOUTBUF
#define NONE

In the current release, that should not be necessary, as the header that defines those is included automatically when analyzing the source and generating the stub and skeleton code.

Hi Daniel,

thanks for your answer.

I use C6run 0.94.05.06 which was included in the DVSDK.

After adding the dummy defines, everythings works. I will try to update C6Run and remove the defines.

Thanks a lot.
