Abstract
A method and system for providing frame start indication in a memory system having indeterminate read data latency. The method includes receiving a data transfer and determining if the data transfer includes a frame start indicator. The method also includes capturing the data transfer and “n” subsequent data transfers in response to determining that the data transfer includes a frame start indicator. The data transfer and the “n” subsequent data transfers comprise a data frame.
Claims8
A hub device for providing frame start indication, the hub device comprising:
- a mechanism for receiving data transfers via a channel in a memory system and for determining if a data transfer includes a frame start indicator, the memory system having unpredicted read data latency, the channel comprising an upstream channel and a downstream channel, and the receiving on one of the upstream channel and the downstream channel;
- a mechanism for capturing the data transfer and “n” subsequent data transfers in response to determining that the data transfer includes the frame start indicator, the data transfer and the “n” subsequent data transfers comprising a data frame, wherein “n” is greater than zero;
- and
- a mechanism for transmitting the data frames via the channel, each transmitted data frame including a frame start indicator.
A method for providing frame start indication, the method comprising:
- receiving a data transfer via a channel in a memory system, the memory system having unpredicted read data latency, the channel configured to transfer data in an upstream direction and a downstream direction;
- determining if the data transfer includes a frame start indicator;
- and
- capturing the data transfer and “n” subsequent data transfers in response to determining that the data transfer includes a frame start indicator, the data transfer and the “n” subsequent data transfers comprising a data frame, wherein “n” is greater than zero.
