Verilog Code, Simulation and Testbench for Project

I need verilog code,testbench and simulation for this duty : Design a vector processing system that performs dot product of two vectors kept in the memory. The length of the vector is given as an input and at each clock cycle one element from each vector is multiplied and added. At the end of the processing a valid signal will be raised along with the result. Elements of the vectors are 8-bit unsigned vectors.
