PROBLEM TO BE SOLVED: To provide a bit array conversion method which can simultaneously process plural data in a small number of processing steps. SOLUTION: A system 100 that carries out this bit array conversion method includes the 1st and 2nd registers 21 and 22 which store the 1st and 2nd data having same number of bits, a register part 20 having a 3rd register 23 and an array conversion control part 40. The control part 40 repeats a 1st instruction to shift the 1st data by one bit in the higher order direction, to store a single overflowed bit in the register 23 and to shift the data on the register 23 to the least significant bit position of the 1st register 21 and a 2nd instruction to shift the 2nd data by one bit in the lower order direction, to store a single overflowed bit in the register 23 and to shift the data on the register 23 to the most significant position of the 2nd register 22 in number of times equal to the number of bits of registers 21 and 22 respectively and finally executes the 1st instruction to the register 21. |
