PURPOSE:To shorten the time of operation, by carrying down by one the address index of a memory which is used as the basis for the operation in order to feed and store the latest data to an address storing the first data. CONSTITUTION:The latest data is stored in an address storing the first, i.e., the oldest data to replace the data. At the same time, the storage of the first data is informed to an arithmetic unit C via an address pointer storing the latest data. Referring to this information, the unit C draws out the prescribed data. This is equivalent to the fact that the connections a1, a2- and b0, b1- are all shifted to the unit C without varying the contents of the data stored in each address of the memory excepting the replacement between the first and latest data and after forming the memory into an endless type by connecting the head and the tail of the memory. |
