C6678 linux concept

dariush karami

At first I should tell a breif history about my project:

I would like to implement an algorithm by parallel programming on C6678 I should mentioned that I implemented my algorithm on desktop processor (intel core i7 3930) by Openmp in Visual Studio before.

So, I used "image_proc_omp" as my base project and implemented as below:

1) I made three threads for receiving packets, parsing packets and store data in DDR3 and processing the data.

2) I synchronized the treads by semaphore.

All things worked good until I would like to use OpenMP in my processing thread. OpenMP didn't work because SYS/BIOS didn't support OpenMP.

Now, I find LINUXMCDSK for C66x.

Question 1:

If I use LINUXMCDSK can I use OpenMP in a thread? Does linux handle my problem?

Question 2:

(I want to load my program on core_0 and processing thread go parallel. What is your opinion about my architecture?

Question 2:

Does linux handle cache problems like cache coherency...?

I moved your thread to the device forum to get a better response.

I hope you are referring C66x linux on DSP from below link. Please confirm.

I do not think, it has support to OpenMP and moreover it is a very old release and no plans for further development on this.

Thank you.

Hi, Dariush,

You may want to consider Ti AM572x instead which has 2 ARM cores and 2 C66x DSP cores. On the ARM core, it support Linux, not ucLinux as on C6678. Your porting will be easier to ARM core.
