    Fast minimization time, compact area and low delay are important issues in logic circuit design. In order to orchestrate these main goals, in this paper we propose a new four level logic form ({\em Generalized EXOR-Projected Sum of Products}, in short {\em GEP-SOP}) with low delay and compact area. Even if the problem of finding an optimal GEP-SOPs is computationally hard, we propose an efficient approximation algorithm that gives guaranteed near optimal solutions. A wide set of experimental results confirms that the GEP-SOP forms are often more compact than the SOP forms, and their synthesis is always a very fast reoptimization phase after SOP minimization.
