Abstract
A data processing apparatus and method are provided for converting data values from a first endian format to a second endian format. Swizzle circuitry is provided for receiving a block of data containing at least one data value, and for converting each data value from the first endian format to the second endian format. The swizzle circuitry comprises first swizzle circuitry for performing a re-ordering operation on the block of data assuming the at least one data value contained therein is of a first size, in order to produce re-ordered data. Second swizzle circuitry is provided which is responsive to an indication that the at least one data value is of a size different to the first size to perform an additional re-ordering operation on the re-ordered data having regard to the size of the at least one data value in order to convert each data value to the second endian format.
