ABSTRACT:
An arrangement for shifting packed data is provided, in which packed data have multiple partial data each having n-byte, n being an integer greater or equal 1. The arrangement comprises: a shifter for shifting the packed data by a predetermined number of bits, a mask generator for generating a mask having multiple n-byte masks concatenated to the size of the packed data, and a logical unit for logically combining said mask with said shifted packed data to generate individually shifted partial data.
