    摘要: Configurable CRC calculation engines and methods of performing CRC calculations are presented. The configurable CRC calculation engines calculate a CRC value for the data using an associated polynomial and remainder. The method includes receiving a polynomial, receiving a block of data to determine a CRC value for, and calculating a CRC value for the data using the polynomial. With such devices and methods, the configurable CRC calculation engines are useful in various applications and protocols.

    摘要: An arrangement is provided for performing Montgomery multiplications. A Montgomery multiplication comprises a plurality of iterations of basic operations (e.g., carry-save additions), and is performed by a Montgomery multiplication engine (MME). Basic operations in each iteration may be performed by multiple Montgomery multiplication processing elements (MMPEs). An MME may be arranged to pipeline the process of performing iterations of multiple basic operations and other operations required to complete a Montgomery multiplication both horizontally and vertically. An MME may also be arranged to interleave processes of performing two Montgomery multiplications.
