PURPOSE:To eliminate the need to correct a program and debug attending on the correction by correcting only a constant table stored in a constant table memory at the same of state transition variation. CONSTITUTION:An SIO (serial input/output controller) 2 is connected to a CPU1 through an interface 3, and the memory consisting of a system program memory 6, data memory 5, and constant table memory 4 is connected. The constant table memory 4 is stored with a transition factor analytical table which contains transition factor data corresponding to respective internal states of a state transition table and starting address data of a processing program corresponding to said transition factor data as a constant table and only the constant table is corrected at the time of state transition variation. |
