Hi

 

I need prove/explain why a Intel Celeron 1.8GHz (a general propouse processor) with SUSe Linux is faster than a Blackfin 537 with uClinux (audio and video processor) to execute a image process task. Celeron is 10x faster than blackfin (the same code, compiled with gcc and gcc-crosscompiler).

 

Ok, frequency can be a reason... but 10x is a big difference, there are more reasons. I'm trying understand what's happening.

 

Are there some ideas why it occurr?

 

Regards,

 

Glauber

Lets see : memory bandwidth, L2 cache, different instruction set, floating point support, raw CPU speed, compiler efficiency - there can be lots of reasons.
