Abstract
A data processing apparatusincludes bridge circuitrywhich serves to translate memory transactions of a first type (AXI) into memory transactions of a second type (PCI Express). The bridge circuitry includes translation circuitrywhich maps at least some of the bits of attribute data of a memory transaction of the first type to unused bits within the significant bits of an address of the second type, which are unused to represent significant bits of the address of memory transactions of the first type.
