Aimed at the MAC design in DSP system with standard CMOS library

this paper presents the idea of constructing the general MAC platform based on the minimal merging of multi-mode multiplications

which can well satisfy all kinds of DSP requirements and improve the efficiency of system.To achieve the perfect match with multi-pipeline DSP architecture

the idea of partition of the platform is also put up.As an example

a 16 bits DSP's MAC platform is illustrated in the paper.It applies the novel methods of Booth encoding combined with partial products generating

forwarding round disposal and selected realization of Wallace-tree adding to its optimization.Through the synthesis of MAC circuit

it validates that the ideas and methods presented in the paper do well to reduce the critical path delay and circuit gates.
