Abstract
An elastic-type first-in-first-out (FIFO) buffer network for an input/output interface to enable higher link layer clock frequencies given fixed transmit clock frequencies of these “parallel-serial” high speed link interfaces. The network is particularly applicable to interface components used in InfiniBand type hardware.
Claims20
A core for providing communications between a transmission media and a processor in a parallel-serial architecture, said core comprising:
- a logic layer;
- at least one serial lane connecting said logic layer to said transmission media;
- and
- at least one buffer interposed in each serial lane,
- wherein each buffer corrects for fluctuations in said transmission media and alters a frequency of signals being processed along said serial lanes.
A parallel-serial architecture network comprising a transmission media and at least one processor connected to said transmission media by a core, said core providing communications between said transmission media and said processor, said core comprising:
- a logic layer;
- a plurality of serial lanes connecting said logic layer to said transmission media;
- and
- a plurality of receive buffers and transmit buffers within said serial lanes,
- wherein said receive buffers and said transmit buffers alter a frequency of signals being processed along said serial lanes.
A core for providing communications between a transmission media and a processor in a byte-stripped parallel-serial InfiniBand architecture, said core comprising:
- a logic layer;
- a plurality of serial lanes connecting said logic layer to said transmission media;
- and
- a plurality of receive buffers and transmit buffers within said serial lanes,
- wherein said receive buffers correct for fluctuations in said transmission media and alter a frequency of signals being processed along said serial lanes.
