This paper presents the design and implementation of a reciprocal unit, in which the initial approximation of the reciprocal is obtained using a look-up table and a multiplication. How to create a look-up Table efficiently is described in detail, and the error analysis for the ROMs of different sizes is also given in this paper. The presented design utilizes a 27
