Abstract
Abstract An electronic calculator is disclosed having an entry unit with a keyboard which can be utilized either to store data in or to retrieve data from a storage unit with a plurality of storage elements. Entries can be made in the keyboard to produce store, address, and readdress indicator signals as well as data and addresses. An entry detector is provided to develop and store signals in response to the type of entries made in the keyboard. An address transfer unit is provided to receive addresses from the entry unit and addresses retrieved from the storage unit. In response to the signals developed by the entry detector, a transfer control unit operates to cause an address produced by the entry unit to locate a storage element in the storage unit either by directly addressing, or by indirectly addressing, or by successively indirectly addressing storage elements in the storage unit. Both data retrieved from the storage unit and data transferred from the entry unit can be utilized by an arithemtic unit in performing calculations.
