% function [data32] = loadhex32(infilex, infiley, N)
% load two 16 bit hex files generated by dspdebugger, the first file contains
% x data and the second file contains y data. This program combines 
% the two data file and return a decimal array of 32 bit data value,
% and plot it. The two 16 bit hex files should have the same address range for
% most case unless special arranged data otherwise.
% input: filename (infile) and number of characters in a row (N)
%			Usually, N is 20.
