PURPOSE:To reduce memory capacity, and to realize a small-capacity and inexpensive control system by providing a data processing means which combines and stores properly a large amount of dta required for precision improvement and restores them. CONSTITUTION:Continuous input quantities are encoded at a specific period, the encoded data are processed, and the resulting data after the processing are combined together and stored. The stored data when used is converted into plural data corresponding to the encoded data so that they can be used. For example, a continuous input quantity (r) is sampled by a sample and hold circuit 1 at the constant period, and its output signal r0 is converted by an A/D converter 2 into a binary code, which is inputted to a CPU3. The code is processed under the control of the CPU3 according to a control program stored in an ROM4 and stored in an RAM5, and the data when used is converted into plural usable data. |
