The AXI to PCI bridge is implemented in the Northbridge.
|Memory base address|
|DMA||None. Memory to memory transfers can be set up in the DMAC.|
|Release version||NEC (AXI2PCI)|
The windows that provide access to the PCI expansion bus are listed in Table 4.43.
|PCI I/O window|
|PCI Memory window|
The AXI to PCI bridge enables you to use the PB11MPCore with third-party PCI or PCI-Express expansion cards. PB11MPCore functions as a PCI host, that is, it generates clocks to the PCI or PCI-Express card.
The Northbridge AXI to PCI bridge recognizes accesses to addresses
the memory map as being intended for a target within PCI address space.
There is also an additional region from
is reserved for PCI expansion if required.
Only one PCI bus may use the I/O window at a time, as it is 4KB aligned.
PCI bridge initialization and configuration routines are included as part of the selftest suite on the Versatile Family CD.
