Hi All,

What is the cache line size of a TMS320C6678 ?

I just need to that to avoid false sharing when using OpenMP ....  (one array being updated by multiple threads although each thread updates a different element of the array, however, since the cache lines is loaded/unloaded after each element update, there is chance for dirty read/write).

I found the below from DSP Cache User Guide ... saying that it is a 32-bye cache line... 

Any comment is much appreciate it. Please let me know if this is the right value ...

Regards,
