Scalable channel bundling with adaptable channel synchronization |
摘要 |
Structures and methods to facilitate channel bundling are disclosed. In one embodiment, signal distribution circuitry includes a data path with at least two registers coupled to adjacent sets of data channels in a bundle of data channel sets. In another embodiment, self-switch circuits allow channels in a bundle of channel-sets to switch from bundle-wide signals to locally generated signals after the bundle-wide signals have been synchronously distributed to all channel sets in the bundle. In a particular embodiment, signal distribution circuitry is used to distribute a divided clock signal. In another particular embodiment, signal distribution circuitry is used to distribute enable signals for first-in first-out circuits (“FIFOs”) located in channels of each data channel set in a channel set bundle. In a particular aspect of an embodiment, FIFO read and write operations across a channel set bundle are initiated such that a difference between read and write pointer signals is the same in each channel set. |
