IPC SYSLink or DSPLink Omap L137

Other Parts Discussed in Thread: SYSBIOS, OMAPL138

Hello everyone.

we are using OMAP L137, our first step in the project is to read a file from the sd card, do some processing and then store back on the sd card.

Is this possible and if it is, what is the best approach: IPC , SYSLink or DSPLink

The next step of the project is to get an audio input, do some processing, and store the data or output the data

Again what would the best approach be.

Thank you,

Kassem.

Kassem,

SYSLINK/IPC based solution is the next generation of DSPLINK. If you look at syslink documentation, there is no mention of support for OMAPL137 devices as the base package provided doesn`t support this platform so sticking to DSPLINK may be your best option.If you do opt to port Syslink for OMAPL137, you are most likely to run into issue like the ones discussed here:

http://e2e.ti.com/support/embedded/bios/f/355/t/137755.aspx

Moreover SYSBIOS is required on the DSP with SYSLINK on OMAPL137, and there is no DSP driver support using SYSBIOS.

If you do decide to use DSPLINK, there are two examples that I know of which will be a good starting point for you

1. Example application to call into DSPLIB functions using DSPLINK and DSPL BIOS:

2. Audio SOC example (This is validated on OMAPL138 but should be portable to OMAPL137)

If you have any issues with the software, please post your questions in appropriate forum in the Embedded software forums(BIOS, LINUX)

Hope this helps.

Best Regards,

Rahul
