<p>A variable-length bit data processing circuit includes first, second and third one-word registers (12, 20, 22). Data from a memory is loaded to the first register (12), and variable-length bit data is taken out from the third register (22). The second and theird registers (20, 22) are coupled with a barrel shifter (16), which shifts two-words of data in accordance with barrel shift quantity data based on the number of effective bits and remaining bits obtained from a subtracter (30).</p> |
