PURPOSE:To perform the multiple branch without an input line and a selector exclusive for multiple branch, by using already provided hardware existing in an information processing device and inputting data selectively from each position and storing it. CONSTITUTION:When the multiple branch is indicated by a micro instruction set to a micro instruction register 2, plural kinds of data are outputted to a line 15 in accordance with the state of data given to a storage means 3. Plural kinds of address are outputted to lines 16 and 18 also. Thus, the multiple branch is performed. Data can be set to a register 37 from each position through a line 31 by registers 32 and 33, a driver 34, and a driver/receiver 36. m-number of bits out of data set in this manner are separated and outputted to a line 38. This m-bit data becomes an m-bit output of the storage means 3 and is inputted to an OR gate 5. |
