Abstract :
This paper proposes a novel architecture of the convolver which can also be used as a correlator (depend on the order in which the input sequence are put in). It is power and area efficient compared with the typical architectures based on registers. Two groups of convolver are implemented to show the improvement. One group deals with two 12 bit data sequences of length 64, while another deals with two 12 bit data sequences of length 256, with each group containing a ram based one and a conventional one. The synthesis results by DC using SMIC 0.13 um library and the results of Prime Power shows that in the second group, the area and power of the ram based one can be reduced to 91% and only 77% of the conventional one, respectively.
