摘要： A method and an apparatus for communication among multiple devices on a data bus with relatively few connections to the bus and reduced logic for enumeration, arbitration, and data flow control is described. A Very Little Multi Master Bus (VLMMB) couples various devices in a bit-rotated manner. When one or more devices seek ownership (control) of the bus, that device raises its assigned bus request line to a predetermined logic (e.g., “1” or “0”). Because there are as many bus request lines as devices, each device can “see” the devices requesting the ownership of the bus. If multiple devices request ownership, the requesting devices determine which one gains ownership by a hierarchical, round-robin, or similar logical decision.

摘要： A low overhead method to handle inter process and peer to peer communication. A queue manager is used to create a list of messages with minimal configuration overhead. A hardware queue can be connected to another software task owned by the same core or a different processor core, or connected to a hardware DMA peripheral. There is no limitation on how many messages can be queued between the producer and consumer cores. The low latency interrupt generation to the processor cores is handled by an accumulator inside the QMSS which can be configured to generate interrupts based on a programmable threshold of descriptors in a queue. The accumulator thus removes the polling overhead from software and boosts performance by doing the descriptor pops and message transfer in the background.

摘要： A serial communications interface is described that enables the extension of an internal Communications Bus Architecture (CBA) bus segment to one or more external devices. The interface accomplishes this function by serializing bus transactions in one device, transferring the serial transaction between devices via one interface port, and de-serializing the transaction in the external device. The general features include low pin count (as few as three signals), simple packet based transfer protocol for memory mapped access, symmetric operation, simple block code formatting, supports both host to peripheral and peer to peer transactions, and support multiple outstanding transactions.
摘要翻译：描述了能够将内部通信总线架构（CBA）总线段扩展到一个或多个外部设备的串行通信接口。该接口通过串行化一个设备中的总线事务，通过一个接口端口在设备之间传输串行事务以及在外部设备中反序列化事务来完成此功能。一般功能包括低引脚数（少至三个信号），用于存储器映射访问的简单的基于分组的传输协议，对称操作，简单的块代码格式化，支持主机到外设和对等交易，并支持多个未完成的事务。
