    摘要: A serial communications protocol is provided that has mandatory features such as an idle code feature and optional features such as an optional automatic lane polarity reversal feature and an optional automatic lane order reversal feature, an optional clock tolerance compensation feature, an optional flow control feature, and an optional retry-on-error feature. A user that desires to create a protocol-compliant integrated circuit design can either choose to include or to not include the optional features. Integrated circuits in which the optional features are implemented are able to perform the associated functions. Integrated circuits in which the optional features have not been implemented are not able to perform these functions, but can be fabricated using fewer circuit resources.

    摘要: Integrated circuits compliant with a serial communications protocol with optional and adjustable features are provided. Tools for designing such circuits are also provided. The protocol supports different data transmission modes such as streaming data and packetized data. A regular data port and priority data port may be provided so that priority data may be nested inside regular data during transmission. Various levels of data integrity protection may be provided. If no data integrity protection is desired, a user can opt to omit data integrity protection from a given integrated circuit design, thereby conserving resources. If data integrity protection is desired, the user can select from different available levels of data integrity protection. Data may be multiplexed using user-defined data channels.

    摘要: Integrated circuits compliant with a serial communications protocol with optional features are provided. The optional features include control plane features such as flow control, retry-on-error, clock tolerance compensation, and idle codes and include data path features such as streaming and packetized data modes, configurable data ports and user-defined data channel multiplexing. An integrated circuit compliant with the protocol can transmit streaming data with or without clock tolerance compensation codes. A priority data port can be used to implement retry-on-error functions while user-defined data channels carry user data. The data ports can be individually configured to perform different levels of cyclic redundancy checking. Logic design tools are used to create compliant circuits and systems.
