Talk:RapidIO

In line citations

I rewrote this article so that folks could quickly learn about RapidIO. Everything in the article related to the history of RapidIO and the RapidIO specification is based on the cited RapidIO book and/or the specification. I'm quite willing to add specific citations to every sentence if that's what is necessary to demonstrate verifiability and neutrality.

As for "may rely excessively on sources too closely associated with the subject", seriously? Only those ignorant of a subject can write Wikipedia articles? :) I welcome others contributions to this article and suggestions for improvements/additions...

Cheers,

Competing Technologies - Proposed Change

I'd like to remove the reference to IEEE 1355 from the RapidIO page. Comments?

I would not view IEEE 1355 as a competing technology, as IEEE 1355 seems to be optimized for lower speed links and devices. There are a large number of other low speed control technologies developed for a variety of industries, including CANBus, RS232 and other UART standards, LIN, FlexRay, MOST, EtherCAT and so on, which I also would not view as competing technologies.

If anyything, IEEE 1355/SpaceWire is a complimentary technology to RapidIO. Having studied an implementation, and made presentations on the subject, it is straightforward to bridge between SpaceWire and RapidIO.

I think a stronger claim for being a competing technology in space may be SpaceFibre (http://www.star-dundee.com/knowledge-base/spacewire-and-spacefibre), as the space community has recognized a need for higher bandwidth communications. The SpaceFibre standard is in development at this time. I would encourage the SpaceFibre developers to add a SpaceFibre page to Wikipedia.

Cheers, Barry

I think I wrote the now-removed edit comparing IEEE-1355. I agree that the original standard's speeds are no longer competitive. However, speed is not the main advantage of RapidIO. (OC-176 and 100Gbe are faster, of course.) 1355 competes with RapidIO with simpler, potentially-faster, lower-power designs for hardware routing, congestion-control and link recovery. These are all independent of the phy layer, just as RapidIO's methods are. If SpaceFibre competes in any RapidIO application, then one endorses 1355 as competition. SpaceFibre is a faster phy for SpaceWire, and therefore a faster phy for IEEE-1355. I hope you will consider restoring the competitive comparison. Ray Van De Walker 21:12, 18 November 2014 (UTC)

Rewrite for 3.0

This article needs to be revised to - provide an overview of the RapidIO specification - identify RapidIO's strengths and weaknesses compared to other interconnects - provide some marketing information for RapidIO's current market wins and direction — Preceding unsigned comment added by Barrywood568 (talk • contribs) 11:50, 21 October 2013 (UTC)

Verification

This article needs to be expanded on SRIO vs Par RIO. It also needs to be checked for accuracy, as I don't trust it.

This input has been reviewed and checked by the RapidIO Trade Association, as of Jan 2008. Thomaslcox (talk) 15:22, 15 January 2008 (UTC)

== Comparison article suggestions == azzo

Here is are a couple of resources comparing PCI Express & others to RapidIO, in some technical detail. Perhaps those here with more experience with the two can tell whether they are correct and useful resources for the links here. --jwilkinson 19:20, 11 July 2007 (UTC)

How RapidIO and PCI Express compare, by Ralf Lehmann

RapidIO Technology, PCI Express and Gigabit Ethernet Comparison Presentation, a PDF on RapidIO.org, more marketing based.

Instead of linking directly to the PDF, It might be more useful to link to RapidIO Technology Comparisons.

Mention SRIO Cores and/or SRIO interfaces?

Should the SRIO page have a section discussing or listing available SRIO interface or bridge/switch components, cores, etc? Is that appropriate here? --jwilkinson 20:47, 7 September 2007 (UTC)

doorbell, funny

the phrase "doorbell-style interrupts" links to both "doorbell" and "interrupt" but neither pages exaplain what a doorbell-style interrupt actually is.

I added a doorbell interrupt section to the Interrupt page and linked this article to that new section.

The doorbell page also links to the Interrupt page now, in case someone searches that term and ends

up on the doorbell page. Brianonn (talk) 07:48, 26 January 2009 (UTC)

End of RapidIO

The RapidIO Trade Association has ceased operations. Is RapidIO no longer being used in new products? Have companies migrated to something else? MP64 (talk) 17:07, 13 January 2024 (UTC)

It's pretty much all either PCIe or 10GbE+ today. --Zac67 (talk) 17:40, 13 January 2024 (UTC)
