<p>PURPOSE:To prevent the miss of data exchange from being generated between processors at the time of an initial instable state by alternatively executing the exchange of start data between the processors three times at least by a data exchanging means and executing synchronous start. CONSTITUTION:Two processors 1 and 2 and a dual port RAM 3 as the data exchanging means are provided. When reset is loaded to the processors 1 and 2, the exchange of 1st code - 3rd code as the start data is alternatively executed three times at least between the processors 1 and 2 by the dual port RAM 3 and after that, the processors 1 and 2 are synchronously started. Thus, it is not necessary to wait processing for a useless time to consider the dispersion of the processor. then, since the processors are started after real rising, the exchange miss of the data is prevented from being generated between the processors 1 and 2 at the time of the initial instable state.</p> |
