Abstract
A microprogram controlled operator device is described which processes bytes each of which is comprised of an equal number of binary-coded decimal figures. The device comprises first and second byte stores each of a multi-byte capacity, a logical and arithmetical operator circuit having inputs connected to read-out outputs of said stores and having an output to a buffer register and code handling organization, preferably further enabling "raw" byte inputting. An output of the code handling organization is connected to an input of a byte code processing arrangement which includes a multiplexer circuit having outputs to write-in inputs of the first and second stores and having further inputs connected to external data supplying means and to read-out outputs from the said stores. The organization further has an output to the external equipment wherein said device is connected.
