摘要： The present invention provides for an on-chip communications method with fully distributed control combining a fully-pipelined, fixed-latency, synchronous bus with a two-level arbitration scheme where the first level of arbitration is a framed, time-division-multiplexing arbitration scheme and the second level is a fairly-allocated round-robin scheme implemented using a token-passing mechanism. Both the latency and the bandwidth allocation are software programmable in real-time operation of the system. The present invention also provides for a communications system where access to a shared resource is controlled by the above communications protocol. Access to and from the shared resource from the subsystem is through a bus interface module. The bus interface modules provide a level of indirection between the subsystem to be connected and the shared resource. This allows the decoupling of system performance requirements from subsystem requirements. Communication over the bus is fully memory mapped.
摘要翻译：本发明提供一种片上通信方法，其具有完全分布式控制，其将完全流水线的，固定等待时间的同步总线与两级仲裁方案组合，其中第一级仲裁是成帧的时分复用仲裁方案，第二级是使用令牌传递机制实现的相当分配的循环方案。延迟和带宽分配都可以通过系统的实时操作进行软件编程。本发明还提供一种其中对共享资源的访问由上述通信协议控制的通信系统。从子系统访问和从共享资源访问通过总线接口模块。总线接口模块提供要连接的子系统与共享资源之间的间接级别。这允许系统性能要求与子系统要求脱钩。通过总线通讯完全记忆映射。

摘要： A core block with a highly configurable interface such that the interface of the core can be optimally configured for the system the core is integrated into. In one embodiment the method consists of defining a configurable interface with different configuration options, capturing the specific core configuration through manual entry or through the use of a Graphical User Interface, and providing for software that combines the source description of the core with the configuration data to generate the core with an optimally configured logic and circuit interface.

摘要： A communication system. One embodiment includes at least two functional blocks, wherein an first functional block communicates with a second functional block by establishing a connection, wherein a connection is a logical state in which data may pass between the first functional block and the second functional block. One embodiment includes a bus coupled to each of the functional blocks and configured to carry a plurality of signals. The plurality of signals includes a connection identifier that indicates a particular connection that a data transfer is part of, and a thread identifier that indicates a transaction stream that the data transfer is part of.

摘要： Embodiments of apparatuses, systems, and methods are described for composing on-chip interconnects with configurable interfaces. A configurable interface includes a configurable agent and interface port. The configurable agent has a first input and a first output with the first input receiving a first communication. An input of a core receives the configurable agent's first output. The agent is configured for important inter-network characteristics such as topology, flooding control, clocking/reset, and performance enhancement.
