Abstract
An apparatus and method for efficiently transferring a plurality of segmented data with various sizes. An address translation storage unit stores an address translation table which provides a plurality of translation descriptor domains to support a plurality of translation step sizes. Depending on the segment size of each data block to be transferred, a translation descriptor domain selection unit chooses a suitable translation descriptor domain within the address translation table. Data segment mapping is then performed with translation descriptors in the selected translation descriptor domain.
