FIELD: engineering of data processing systems, which realize operations of type "one command stream and multiple data streams".
SUBSTANCE: system is disclosed with command (ADD8TO16), which decompresses non-adjacent parts of data word with utilization of signed or zero expansion and combines them by means of arithmetic operation "one command stream, multiple data streams", such as adding, performed in response to one and the same command. Command is especially useful for utilization in systems having a data channel, containing a shifting circuit before the arithmetic circuit.
EFFECT: possible use for existing processing resources in data processing system in a more efficient way.
