Method and the device of the redundant technique in controller designing which designates the processor as the base

摘要

The system which processes the data of process the primary controller (30) and the redundant controller (40) of making use (20). The primary controller (30) the primary processor is included, this primary processor, in order to execute the task of data tracking, is operation possible, in order to remember the tracking data in toratsuka memory, using the low-speed bus, the toratsuka controller (32) and also it works. The primary processor furthermore in order to execute other task primary memory (32) and also by using the high-speed bus which works, is operation possible. For example 2nd the bus (37), 1st the bus (38) a considerably faster operating speed (, 2 times or more) it possesses.
