    Abstract: A chip configuration for dual board voltage compatibility comprising ballast I/O pads, regulator control block and VDDCO pad. If 1.8V is available on board, all 1.8V pads are connected to the package pins and the VDDCO pad is double bonded with one 1.8V package pin. This ensures that the regulator is in operation providing 1.2V supply to the core. If 1.2V is available on board, all 1.2V pads are bonded to the package pins and VDDCO pad is left unbonded. A weak pulldown ensures that the regulator is inoperational and the gate voltage of ballast transistor is pulled up. Now 1.2V pads directly get supply from the board through package pins and is provided to the core without suffering IR drop.

    Abstract: A method employing an improved rate-matching algorithm used during transmission and reception of information packets involves performance of a complete process of puncturing or repetition in two steps. In the first step the action to be taken on each bit of the input register is calculated and is stored in the form of flag bits in flag register. In step 2, puncturing/repetition are performed on input bits and the output is stored in output register. Input bits can be processed in groups in step 2, reducing the number of steps required in the complete rate matching process.
