Abstract
Herein are disclosed computation units for element approximation. A computation unit may include a first circuit to compute a first projection π of an input element xi from a first range to a second range. In the first circuit, the input element xi may have a first format and the projected element yi may have a second format. In addition, in the first circuit, the second format may have more bits than the first format. The computation unit may further include a second circuit operatively coupled to the first circuit to produce a reduction zi in the first format using the projected element yi in the second format. The computation unit may also include a third circuit operatively coupled to the second circuit to compute a second projection ρ of the reduction zi from the second range to the first range to produce an approximation wi.
