Index into 32 bit word to extract relevant data

I have an array of 32 bit words created by reading from a binary file. Each 32 bit word contains 12 bits of I(in-phase) and 12 bits of Q(quad-phase) data. What is the most efficient way to extract the IQ data to create an array of complex data?

Use the bit-wise operations functions or use rem, mod, subtraction, and division.
