PROBLEM TO BE SOLVED: To provide a command control system that can execute a command processing at high speed in a command control system of an out-of-order system. SOLUTION: A general purpose register address outputted from a command register 20 is reread by a register update buffer address corresponding to an update table 22. Also, an update holding instruction bit corresponding to this general purpose register address is read from a register update holding table and, when it is '0', a general purpose register address is given to a general purpose register 26 and data stored in the address is supplied to an operator 35. On the other hand, when the update holding instruction bit is '1', contents of an entry concerned of the update table 22 is registered with a reservation station 33. In the reservation station 33, an execution sequence of each entry is decided, a register update buffer address is given to a sequential register update buffer 25 and data stored in the address is supplied to the operator 35. |
