    • The present invention relates to a data pipeline management system and more particularly to a minimum memory solution for unidirectional data pipeline management in a situation where both the Producer and Consumer need asynchronous access to the pipeline, data is non-atomic, and only the last complete (and validated) received message is relevant and once a data read from/write to the pipeline is initiated, that data must be completely processed. The data pipeline management system according to the invention can be implemented as a circular queue of as little as three entries and an additional handshake mechanism, implemented as a set of indices that can fit in a minimum of six bits (2×2+2×1). Both the Producer and Consumer will have a 2 bit index indicating where they are in the queue, and a 1 bit binary value indicating a special situation. Both parties can read all the indices but can only write their own, i.e. P and wrapP for the Producer and C and wrapC for the Consumer. For management of the handshakes a set of rules is provided.
    • 本发明涉及一种数据流水线管理系统,更具体地说,涉及在生产者和消费者都需要对流水线进行异步访问的情况下,用于单向数据流水线管理的最小存储器解决方案,数据是非原子的,并且仅最后完成 (和验证的)接收到的消息是相关的,并且一旦从/写入管道的数据被发起,则该数据必须被完全处理。 根据本发明的数据流水线管理系统可以被实现为只有三个条目的循环队列和另外的握手机制,被实现为可以适合于最少六位(2x2 + 2x1)的一组索引。 生产商和消费者都将有一个2位索引,指示它们在队列中的位置,以及一个表示特殊情况的二进制值。 双方都可以读取所有的索引,但只能为生产者编写自己的P和wrapP,为消费者编写C和wrapC。 为了管理握手,提供了一套规则。
