摘要
Embodiments are directed to a method of accessing a data frame, wherein a first portion of the data frame is in a first memory block, and wherein a second portion of the data frame is in a second memory block. The method includes determining that an access of the data frame crosses a boundary between the first second memory blocks, determining that an attempted translation of an address of the first portion of the data frame in the first memory block did not result in a translation fault, and accessing the first portion of the data frame. The method further includes, based at least in part on a determination that an attempted translation of an address of the second portion of the data frame in the second memory block resulted in a translation fault, accessing at least one default character as a replacement for accessing the second portion of the data frame.
