<p>PURPOSE:To provide a microprocessor which can lengthen the time permitted for carry propagation. CONSTITUTION:A first shift register 17 is connected with a data bus 14, each bit is inputted from the external part and latched. One side input side of a computing element 19 is connected with the first shift register 17, and other side input side of the computing element 19 is connected with a second shift register 18. The computing element 19 inputs the data of each 1 bit from first or second shift register 17 and 18 and performs respective kinds of operation. The output side of the computing element 19 is connected with the second shift register 18 and the data of each 1 bit are sent to the second shift register 18.</p> |
