HyperTransport™ System Architecture

The Address Remapping Capability Block

This capability block allows software to control the HT to expansion bus bridge address for:

• remapping HT I/O address space down to a lower range within an expansion bus.

• remapping HT MMIO space to expansion bus address space.

• remapping HT Memory space to expansion bus address space.

• remapping Bus Master memory transactions from expansion bus address space to HT address space.

Figure 21-2 on page 479 illustrates the format of the Address Remapping capability block. The following sections describe each register and its remapping function.
