摘要： The shift system has rotate parts 12-1 and 12-2 which take divided input data from divided input parts 9-1 and 9-2. Each rotate part 12-1, 12-2 is selectively operable to rotate the divided input data fed thereto and place the rotated data in rotate part outputs 10-1 and 10-2. Select parts 14-1, 14-2 place a selection from the rotated data in rotate part outputs 10-1 and 10-2 in select part output 11, which selection corresponds to the input data shifted by a selected amount. When the rotate parts 12-1, 12-2 rotate data by multiples of 2 A bits only, the selection in select part output 11 corresponds to a shift by a multiple of 2 bits. To effect a shift of the selection in select part output 11 by 0≤Q≤2 A -1 bits, shift parts 16-1 and 16-2 are provided.

摘要翻译： 换档系统具有旋转部分12-1和12-2，其从分割的输入部分9-1和9-2分割输入数据。 每个旋转部分12-1,12-2选择性地可操作以旋转馈送到其中的分割的输入数据，并将旋转的数据放置在旋转部分输出10-1和10-2中。 选择部件14-1,14-2在选择部分输出11中的旋转部分输出10-1和10-2中从旋转的数据中选择选择，该选择对应于移动了选定量的输入数据。 当旋转部分12-1,12-2仅将2×A位的数据旋转数据时，选择部分输出11中的选择对应于2 位的倍数。 为了使选择部​​分输出11中的选择移位0，提供了偏移部分16-1和16-2。
