I am a newbie so I apologize if my questions are banal.
I have done quite a bit (alot) of programming over the last 15 years
in C/C++ on the Intel/DOS platform, dabbled with LINUX but no coding.
Just a few simple GCC "hello world" programs. I am reasonably
proficient tooling around LINUX. I've done quite a bit of 8 bit
microprocessor assembly programming and hardware design too. I've
never compiled a LINUX kernel though.
I am looking into developing a new product that will use raw ethernet
and will bridge packets between two Ethernet interfaces. The program
needs to be able to retransmit Ethernet frames moving from Eth0 to
Eth1 and vice versa as quickly as possible. The program also will
generate packets at line speed (up to 100Mbps) and will need to make a
few decisions along the way that ought not to take too long to do either.
The question is: should I go with ARM (7200) or with Intel (7300)? Is
ARM faster for this sort of application?
If I develop under LINUX, which I am going to do in the initial
prototyping, how hard is it to port a working LINUX C program over to
ARM? Is it harder to work with the TS7300 vs the TS7200? Is the
community more devoted to ARM or Intel?
Any thoughts that any of you may have and would like to share would be
much appreciated.
Mike.
