A dedicated protocol generation unit provides the ability to detect validity of data received from a configurable logic block, such as a programmable logic device (PLD). Data valid signaling is provided by the configurable logic block, such that invalid data received from the configurable logic block is replaced with programmable insertion data prior to transmission, while valid data is allowed to be transmitted without replacement. Also, data received by Input/Output (I/O) portions of the dedicated protocol generation unit are compared to programmable data patterns. After a positive comparison, matching data is either truncated and not delivered to the configurable logic block, or the matching data is delivered to the configurable logic block with appropriate data valid signaling.

Methods and structures of performing multi-level comma detection and alignment on an unaligned data stream. Each string of N consecutive bits in the unaligned data stream is monitored for a predetermined byte value. When the predetermined byte value is located, the unaligned data stream is aligned with the predetermined byte value, producing a partially aligned data stream. A string of bytes from the partially aligned data stream is then compared with a predetermined sequence of byte values. When the predetermined sequence is located, the partially aligned data stream is aligned based on the location of the predetermined sequence within the partially aligned data stream. The invention also encompasses multi-level comma detection and alignment circuits that can perform, for example, the previously described inventive methods.

A system and method for interfacing network elements using an isolated fabric interface module, which is facilitated through exploitation of standards otherwise not specified for the particular networking functions in which they are utilized. Fabric interface functionality is isolated and independent of line and switch fabric cards. Standards otherwise suitable for use in interfacing network elements are adapted for use in the isolated fabric interface configuration. The standard interfaces are adapted to extend beyond the specified length, signal traces are routed according to predetermined routing rules using matched impedance connectors, and signals are terminated to facilitate the length extension. Standard system controllers may also be used although the controlled line cards are not compliant with the standard. A network switching/routing element having a discrete fabric interface module can thus be designed using known standards, while effectively allowing the standards to operate at non-specified parameters.
