Why is offloading IO a bad idea? Offloading video and 3D rendering work
well, it's what drives 3dfx and it's competitors. Or am I missing
something? My basic understanding of I2O is using a subprocessor to
handle all IO, thus freeing up the main processor from doing things like
waiting on interrupts and the like.
3dfx is not offloading io. It's offloading computation to a
special-purpose processor.
Offloading IO can be a good thing in some circumstances if done properly.
I2O was not.
