Abstract
A data processing system using separate fixed point and floating point computation units and a single control store means for controlling the operations of both units, the units being responsive to commonly shared control fields of the microinstructions supplied from the control store means during their respective operations. The floating point unit can provide single or double precision results, an additional control field of the microinstructions identifying which result is required.
