摘要：
A ring buffer in accordance with the invention includes a plurality of registers that form a circular sequence of registers. A write pointer references one of the registers. A plurality of read pointers correspond respectively to a plurality of data consumers. Each read pointer references one of the registers. Upon receiving a new data element, the data element is written to the register that is referenced by the write pointer, and the write pointer is advanced. Upon receiving a request from a data consumer, a data element is read from the register referenced by the read pointer corresponding to the data consumer, and the read pointer is advanced.
