    摘要: A method for formatting ATM cells compliant with SPI-4 Phase 2 specification is presented. The method enables selection among various cell formats depending on the devices employed, and enables use of a payload-only test format, a typical format having payload and header data, a format having header error correction (HEC) data and dummy data, and a format having HEC data and user data.

    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.
