A hardware unit for producing binary orthogonal variable spreading factor (OVSF), Hadamard and Walsh codes for WCDMA/CDMA2000 systems is presented. The generator uses a spreading factor, mode select, and the code index as the control input. The synthesized hardware unit consumes 512 NAND2-equivalent logic gates.
