LogiCORE PCI - Can the I/O space in the PCI core be set to greater than 256 bytes?


General Description:

Can I set the I/O space in my PCI Core to be greater than 256 bytes?


Yes. In the LogiCORE interface, the I/O space may be as small as 16 bytes and as large as 2 Gigabytes.

This is typically required by systems using the PowerPC processors.

Never set this value to be greater than 256 bytes for x86-based systems.
