This document proposes a new fixed point the complex number umnoženi with the accumulation scheme that uses real-time digital signal processing applications. The proposed architecture consists of a multiplier-cum-battery, which can be used as a multiplier, and a MAC. Here the previous MAC result is added as one of the products of partial current multiplication. So the depth multiplier-accumulator block marketing remains the same as O (log2 n) in the case of the Wallace tree multiplier based on a multiplier-cum-battery and O (N) in the case of Braun multiplier based on the cartoonist-cum-battery. And therefore a separate accumulator with depth O (log2 n) can be avoided. The results of the work show proposed architecture that gives better performance than conventional fixed point of a complex number, the proposed MAC architecture provides improved ratio 32.4% of Wallace wood and 19.1% in the Braun multiplier based on the fixed point of a complex number from outside of the pipeline using the library of 45 nm technology. the same architecture provides improved coefficient of 14.6% in the Wallace tree and 12.2% in Braun multiplier based on complex number of fixed point MAC with pipeline.
