Abstract
A main CPU 11 of a Main CPU Module 10 simultaneously sends out control information to respective Sub CPUs 22, 32, . . . , n2, . . . of plural Sub CPU Modules 20, 30, . . . , n0, . . . by broadcast buses 201, 202 of a system bus 200. In the case where control information from the Main CPU sent out through the broadcast buses 201, 202 is control information with respect to corresponding one of Sub CPU Devices 23, 33, . . . , n3, . . . , each Sub CPU carries out operation control of the Sub CPU device on the basis of the corresponding control information. Thus, the Main CPU is not required to finely control processing inherent in the Sub CPU Devices or timings thereof, etc. Also in the case where new Sub CPU Device is supplemented, or Sub CPU Device of different timing is assembled or incorporated into the apparatus, modification of the control program of the Main CPU can be held down to the minimum level. In addition, control program is supplemented to Sub CPU corresponding to Sub CPU Device to be supplemented, thereby making it possible to cope with implementation of such supplement. This editing apparatus can smoothly carry out extension of the apparatus and/or enlargement of scale without lowering performance of the apparatus.
