Abstract

PURPOSE:To make the retrieval processing unnecessary at readout, by making write-in/readout of RAM through the calculation address based on the time information and designated period in a periodical data and the calculation address based on estimated time and period. CONSTITUTION:The time information extracted from write-in data with a time extracting and converting circuit 1 is converted into a second unit time information for the specified operation with the designated period with the reference time and data period storage sections 3, 4, and logical address is calculated at a logical address calculating section 2. This address is compared with the preceding address via a comparator 6, and dummy information is written in the address of a large storage section 11 until arriving at this address and data is written in a counting address section. This information is read out with the estimated second display time converted at a time conversion circuit 12 after the readout of dummy information of succeeding address similarly based on the readout address calculated at the calculation section 2. Thus, daily periodic data are read out from an artificial satellite without retrieval processing and the control with high storage efficiency can be made.
