2009-03-31 04:45:45     BF527 Internal memory

Hi,

 

L1 Memory BF527 has 132 Kbytes against 148 KB of BF533 :

 

What is the expected performance impact due to this?

 

Does it affect the caching performance?

 

Do the drivers use internal memory?

 

Regards,

 

Sudhakar

the SDRAM based Blackfins have all the same performance and cache sizes (ignoring the obvious sub-family variants).  thus there would be no difference whatsoever wrt caches between the BF527 and BF533.

 

some core code / drivers use on-chip L1 memory, but that's all controllable in the configuration menu.  but again, the behavior across the two chips would be exactly the same.
