Are you trying to reduce the overall time taken for a total process
consisting of sense >> Transfer >> Act/Process/respond ? A block
diagram of problem might be instructive. Whats going on at the
client side of this (PC) ?
We are all confused it seems you have a sensor rate of x but need
to transmit results at y >> x which seems counter intuitive.....
Cortex ARM parts many interfaces including USB FS, SPI to 18 Mbps,
even parallel interface, ethernet.....
