Abstract
PURPOSE:To generate writing data coinciding with the boundary of the word of a writing destination by sequentially supplying data rotated by a barrel rotator to first and second registers and combining the data in the first and second registers. CONSTITUTION:The barrel rotator 23 for rotating and outputting the data in a prescribed direction according to a crossing over method when the data to be written or transferred crosses over the boundary of the word of the writing destination and the first register DR0 for storing the data outputted from this barrel rotator 23 are provided. Then, the second register DR1 for storing the previous data outputted from the first register DR0 and a phase mask selector 25 for selecting the output data of the first and second registers DR0, DR1 for every bit according to respective writing positions and synthesizing the writing data thereby are provided. Thereby, the writing data coinciding with the boundary of the word of the writing destination can be formed by moving the bit position of the writing data.
