Ethernet Controller Choices ...????

Started by mall...@yahoo.co.in April 25, 2009
Hi!
we have a designing a custom board which involves Ethernet controller to transfer audio and video data over Network like a webserver.........

I don't have that much knowledge in the software drivers needed for these Ethernet chips....
I want to use either SMSC chips like LAN9218 or Micrel chips like KSZ8851......

I don't know the driver developement side........Whether any drivers are provided for these chips for BF532 interfacing......

In SMSC site, i have seen so many drivers but i can't able to decide what are those,
Like some are showing Wince drivers , Linux some are for SX3 Processor and some are for XSCALE processor.....

we don't have much time to develope our own drivers...
whether any drivers are provided for BF532..or if we want to change or develope existing ones to BF532 what should i do.......
and one more thing in visualDSP they have lwIP, whether i can use that...
Hi,

The question you should ask to yourself is "what throughput I want to
have on Ethernet". With BF532 and a controller tied to the synchronous
memory port you will be limited by bandwidth of memory port; worse the
memory port is shared with SDRAM which means that the cycles that will
be used to commnicate with Ethernet Controller will be stolen from SDRAM
bandwidth. In my experience achieving just 20Mbit on the network was
already eating most of CPU power.
A better choice would be to use BF52x or BF51x familly which have
integrated Ethernet MAC. Internal blackfin MAC is supported by latest
version of lwIP released with VDSP.
