Aspects of the disclosure provide an integrated circuit. The integrated circuit includes a register configured to store multiple data units, a data input generation circuit configured to combine input data for at least partially overwriting the register with the stored multiple data units to generate combined input data, and a clock-gating circuit configured to provide to the register a logically controlled gated clock signal having selectively enabled transitions. The register is overwritten with the combined input data in response to the selectively enabled transitions in the gated clock signal.

Method and apparatus for clock-gating registers

In accordance with the teachings described herein, systems and methods are provided for calculating a Cyclic Redundancy Check (CRC) code for a message. A system includes a first CRC calculator and a second CRC calculator. The first CRC calculator is configured to receive a first data block of the message, and to calculate a first CRC value based at least in part on the first data block, the message including the first data block and a second data block. The second CRC calculator is configured to receive the first CRC value and the second data block of the message, and to calculate a second CRC value based on the first CRC value and the second data block, the second CRC calculator being different from the first CRC calculator.
