Hi,
Does anyone have bulk transfer throughput measurements for any of the EHCI controllers?
Nothing organized, let us know what you find out.
We're looking for controllers that can sustain 32MB/sec in both directions (half duplex of course). Our software radio peripheral can do that using the Intel 82801DB EHCI. We'd like to figure out what other chip sets are likely to be winners or losers.
The original NEC EHCI 0.95 controller won't do that.
I've had reports of almost 48 MByte/sec from a VT8235 (the device was the speed-limiting factor, not the host), and think NForce2 is as good. Likely most newer silicon will handle that data rate.
