TI C6EZAccel library with MityDSP Platform - OmapL138
Added by Michele Canepa almost 12 years ago
Dear Sirs,
does anybody there managed to install and use the C6EZAccel library for the OMAPL138 processor, using the MityDSPL138F carrier board?
It's said to be a library that can abstract Signal Processing libraries of the C647 DSP for the ARM unit, so permitting to call DSP functions directly from ARM program.
TI says that the library has got these dependencies:
"Codec engine: Codec_engine_2_21 and higher
XDCTools: XDCtools_3_10_03 and higher
XDAIS: xdais_6_23
LINUXUTILS: linuxutils_2_23_01
CODE_GEN: cg6x_6_0_21
DSP BIOS
BIOSUTILS
Code sourcery tools
FRAMEWORK COMPONENTs
EDMA LLD
All these dependencies can be found in the DVSDK package for the target platform "
Can someone suggest me how to install these tools in order to run the library?
Does that library provides a different behaviour in terms of efficiency instead of running DSP code through ARM code (as with the HelloWorldDSP example?)
Thank you very much,
Best Regards
Michele Canepa

Hi Michele,
If you would like to use the full TI DVSDK (including C6EZAccel), you can install it from TI (along with the Code Sourcery tool chain). You can use TI's libraries and filesystems, etc. The only thing you will need to do is build using the CL provided kernel, or port our kernel modifications (primarily, the board-mityomapl138.c and the relavent baseboard-industrialio.c files in arch/arm/mach-davinci) over to the kernel snapshot provided by the TI DVSDK. The rest of the EVM filesystems and example programs should then function.
There is a rough notes page regarding this here. It's really not complete, sorry. Please post if you need further assistance. However, CL does not typically use C6EZAccel as most of our applications require more fine grained control over the DSP, so we may need to do a little learning ourselves to help too much.
