    • PURPOSE:To execute saving at the generation of an interruption or resetting at the time of release efficiently, by setting up a vector effective display flag to execute a vector instruction when the flag is on and to generate an interruption at the off of the flag. CONSTITUTION:A scalar instruction or a vector instruction is set up in an instruction register 10. The instruction is decoded by a scalar decoding part 11 or a vector decoding part 12. The scalar instruction is sent from the scalar decoding part 11 to a scalar operating part 8 and the vector instruction is sent from the vector decoding part 12 to a vector operating part 9 through a gate 14. An AND gate 14 is opened when the vector effective display flag 13 is set up. An AND gate 15 is opened when the flag 13 is reset. If the vector instruction is decoded when the AND gate 15 is opened, an interruption controlling part 16 generates and interruption.
    • 目的:为了在释放时产生中断或复位时执行保存,通过设置向量有效显示标志来在标志位置位时执行向量指令,并在标志关闭时产生中断。 构成:在指令寄存器10中建立标量指令或向量指令。该指令由标量解码部分11或向量解码部分12解码。标量指令从标量解码部分11被发送到标量运算 部分8,并且矢量指令通过门14从矢量解码部分12发送到矢量操作部分9.当设置矢量有效显示标志13时,与门14打开。 当标志13被复位时,与门15打开。 如果与门15打开时向量指令被解码,则中断控制部分16产生并中断。
