Scaling Hazards: Burden Is On The Transmitter
It is a requirement in HyperTransport that the transmitter side of each link must be aware of the capabilities of its corresponding receiver and avoid the double hazard of a scalable bus: running at a faster clock rate than the receiver can handle or using a wider data path than the receiver supports. Because the link is not a shared bus, the transmitter side of each device is concerned with the capabilities of only one target. Refer to “Link Initialization” on page 282 for a description of how HyperTransport links are initialized and configured to avoid these problems.
