Low power correlator of DSP core for communication system

The correlator is the most demanded block in a communication systems. In this work, low power correlator block is implemented into an embedded DSP core as a special block. This special block of correlator can employ data bus bandwidth of DSP efficiently. The design results show that it use only 3235 gate counts and can reduce the correlation operations from 20 instructions (without correlator) to only 4 instructions.
