We intend to use simple master slave UDP transfer mode for real time I/O since we are really using this as very simple data pipe (and it needs to stay simple if its to have good real time performance with low cost hardware) UDP (well we support ARP and ICMP-echo and bootp as well) has the advantage that it works just fine with userland TCPIP/UDP stacks so for non-real time applications (buffered motion for example) the same interface works on a normal network. We currently can support 5KHz update rates and I expect to improve this with our next hardware version that has a 16 bit processor embedded in the FPGA instead of 8 bit, perhaps up to 10KHz update rates > -- > atp > If you can't fix it, you don't own it. > http://www.ifixit.com/Manifesto Peter Wallace Mesa Electronics ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
