PURPOSE:To connect CPUs in a high speed by storing an address of a program or the like in a temporary storage means, which is connected to a main CPU, and local memories connected to individual slave CPUs. CONSTITUTION:The start address of a divided program is written in temporary storage means FIFO memories 4 and 5 from a main CPU1 through a data bus DB1. A series of the same programs are stored in the same addresses of local memories 6 and 7 connected to slave CPUs2 and 3, and the same programs can be executed by either of them. By this constitution, CPUs2 and 3 which complete the execution of the current divided program read out the start address of the next divided program from memories 4 and 5 to execute a series of programs. That is, the overhead of time due to communication is reduced to connect CPUs in a high speed. |
