PURPOSE:To exchange the register contents at a high speed without using a main memory unrelated to an original data processing by calculating an exclusive OR corresponding to the bit of the register contents between two different registers, and repeating successively to load the calculated result to the register of either of registers three times. CONSTITUTION:Exclusive OR calculating loading means 20, 30 and 40 as a basic processing means having calculating means 21, 31 and 41 and loading means 22, 32 and 42 are provided and a basic processing is repeated three times. Namely, register contents 1b and register contents 2a are obtained by a first step exclusive OR calculating loading means 20. When the register contents 2a and the register contents 1b are obtained to a second step exclusive OR calculating loading means 30, register contents 2b and the register contents 1b are obtained, and when the register contents 1b and the register contents 2b are inputted to a third step exclusive OR calculating loading means 40, register contents 1c and the register contents 2b are obtained. Thus, the register contents can be exchanged at a high speed. |
