MULTIPLE TRANSACTION DATA FLOW CONTROL UNIT FOR HIGH-SPEED INTERCONNECT

摘要

Methods, apparatus, and systems, for transporting data units comprising multiple pieces of transaction data over high-speed interconnects. A flow control unit, called a KTI (Keizer Technology Interface) Flit, is implemented in a coherent multi-layer protocol supporting coherent memory transactions. The KTI Flit has a basic format that supports use of configurable fields to implement KTI Flits with specific formats that may be used for corresponding transactions. In one aspect, the KTI Flit may be formatted as multiple slots used to support transfer of multiple respective pieces of transaction data in a single Flit. The KTI Flit can also be configured to support various types of transactions and multiple KTI Flits may be combined into packets to support transfer of data such as cache line transfers.
