PURPOSE:To decrease the number of execution registers and to improve the processing capability by providing a register stack storing control information at each channel in a collection channel constituting plural channels. CONSTITUTION:The register stack 11 consists of plural registers, the control information of channel 0 is stored in a register of an address 0 and the control information of a channel 1 is stored in a register of an address 1. That is, the control information of the channel 0 is read from the stack 11 at the cycle 0 and set to the execution register 12-1. The 1st control section 13-1 references the control information of channel 0 to attain processing and updates the control information of the channel 0. The control information of the channel 1 is read from the stack 11 in the cycle 1, set to the register 12-1 and the updated control information of the channel 0 is written in the address 0 of the stack 11. Thus, the number of execution registers is decreased and the processing capability is improved. |
