An HDLC frame formation technique that calculates fields based on unscrambled data and combines unscrambled fields with scrambled data. Decoding HDLC frames includes determining integrity of the scrambled data based on the unscrambled fields.

HDLC encoding and decoding techniques

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.

Asynchronous transfer mode (ATM) cell formatting

A device for mapping and demapping cells in an orderly manner is provided. The device employs a channel identifier and in certain configurations a buffer and series of stages to provide for relatively ordered, predictable mapping and demapping of data, such as virtual concatenation data.

Control mechanism for mapping cells and packets

According to some embodiments, an apparatus is provided comprising a plurality of transmit storage structures each being associated with a storage width, a write block, and a read block. The write block is to receive information having a first width via an interface associated with a configurable width, and the read block is to read the information from the storage structures and is to transmit information to a network line.

Configurable transmit and receive system interfaces for a network device

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.
