thread_title: Merge

message: I think the articles should remain seperate - the systems page has a lot of general information that does not fit in the circuit article.  Kcordina 13:31, 10 March 2006 (UTC)
replies: text: Since no-one has offered further opinion, I have removed the merge tags in line with my opinion. Kcordina  Talk  15:26, 22 March 2006 (UTC)
replies: text: I think they should be merged. There is no information in the systems article that would be inappropriate here. The stuff on design styles, modularity, handshaking protocols, async pipelines are all essential knowledge if you're researching asynchronous circuits. Two of the three references in the systems article actually have "asynchronous circuit" in the title.

thread_title:  Merge with [[Asynchronous Systems]] 

message: I reverted some additions by 172.188.108.141 because they are not strictly true. In the power section the "huge increase in circuit size" is not necessarily present. In fact bundled-data circuits can have a negative overhead due to the removal of clock trees. The Amulet processors was not "cracked" by NDS in Israel. The processor in question is the "SPA" and it wasn't cracked but there was some "information leak" despite its use of balanced dual-rail. Although "there is no significant difference between dual-rail synchronous designs and dual rail asynchronous designs in terms of EMI security" the asynchronous versions are still impermeable to clock glitch attacks.

replies: text: Well at the moment the article says that asynchronous circuits lead to lower power consumption, which isn't strictly true. And while it may be true that one class of attacks has been removed, the use of an asynchronous design does not strictly prevent information leakage, or any other attack. New attacks may be introduced; the clock is a control signal, and when every data line is also a control signal, it may be possible to manipulate them to produce a similar failure. —The preceding unsigned comment was added by 172.188.108.141 (talk) 13:33, 9 May 2007 (UTC)
thread_title:  Corrections by 172.188.108.141 

message: I think the quotes should be removed. Who cares what two guys once said? Neither of them appears to be particularly famous. The Martin rumour should be removed. "Red Star seems to be.." - seems? It either is, or it isn't. The link to UARTs should be removed; asynchronous UARTS are not asynchronous circuits (at least, none that you can buy). Link "asynchronous logic" should be "a.l @ U. of Manchester". Comments? —The preceding unsigned comment was added by 172.188.108.141 (talk) 13:43, 9 May 2007 (UTC)
thread_title:  Removals 

message: First, sorry for taking 3 tries before stopping my edits to this page. It was another case where I saw a couple of things, made an edit, and then things got worse as I went.
Anyway, An Anon Y. Mouse at 68.0.124.33 made 2 edits to the main page on May 5, 2008. While they added substantial new, surface rational, information, they also showed a particularly ugly habit: They made several "flames" in the page, ALL of which were enclosed in XML comment tags so they don't display!  They don't come to the talk page with it, and they know it'll be reverted (and they likely labelled a troll) if they attack another editor in an ARTICLE page! This is the 1st time I've seen this style of (what *I* consider to be) vandalism (he attacked 3 differences items for "not being microprocessors" when no one's claiming they are? Tone is highly harsh and arrogant. I checked their talk page (which *they* didn't set up, surprise, surprise), and they don't appear to have ever attended a Dale Carnegie course. Didn't see a comment by them on their tal page that wasn't hostile, defensive, or both.
Further, it *appears* that computing is their (self-assumed) area of expertise.
Given I've never seen this style of passive-aggressive behavior hidden "in-line" at Wiki, I'll fwd this same note up the creek...   --Grndrush (talk) 00:09, 24 July 2008 (UTC)

thread_title:  Hidden Hostile Additions 

message: There seem to be enough references in the "asynchronous circuit#Asynchronous CPU" section to make asynchronous CPUs notable in their own right.
I suggest splitting out that section into its own article,
leaving behind a brief WP:SUMMARY.

replies: text: Looks like a good proposal, in particular, if you feel that you would like to add significantly more information. Will be some work to properly sort out the references, anyhow. Rainglasz (talk) 15:17, 17 January 2011 (UTC)

text: I think the article is too short to warrant splitting.  Even if the subtopic might be notable, that's not a great reason to split it off instead of expanding here.  Dicklyon (talk) 05:55, 26 January 2011 (UTC)
thread_title:  suggest split 

message: I have added two more items without references, just to start more work on this. The current items are very generic, and do not really cover the problem. 
It will be not easy to find many references, as mostly the books and papers on this subject praise the advantages, not the disadvantages. Nevertheless, citations are to be found, but this may take several weeks.

thread_title:  Disadvantages and Advantages

message: I plan to translate large parts from the article I wrote on the french Wikipedia : I gathered some historical sources as well as schemes and technical informations. I think that the current english article has a lot of lists, and isn't neutral : there are a lot of things about NCL/SCL, like the "recent breakthrough" part, which, in my opinion, are some kind of publicity. Does anyone agree / disagree / want to help ?

thread_title:  External links modified 

message: I have removed the "Dubious - discuss" tag from the claim that synchronous logic is easier to design than asynchronous logic, and inserted a reference to Karl Fant's specific objections. I am not certain if I have done this correctly, and in any case it most likely would need further discussion regarding the claims and counter-claims. If any SME could review this, and make suitable amendments, please do so. --Schol-R-LEA (talk) 00:56, 27 January 2017 (UTC)
thread_title:  "Dubious" tag replaced with reference to specific objection 

message: The page :Synchronous circuit is currently a stub. I was going to c/e content from this article there (more specifically the "Synchronous vs asynchronous logic" section), but it seems to me that both articles would be largely redundant. It should be easy to merge that article into this one content-wise, though I'm unsure how the resulting article should be named. Perhaps "digital circuit"? There is a digital electronics article for which that term currently redirects, in which there are short sections briefly describing synchronous and asynchronous logic, so maybe that's not the best idea. If editors believe a merger would not be beneficial I'll simply c/e from this to that article (the latter is missing some content). Saturnalia0 (talk) 18:24, 5 May 2017 (UTC)
replies: text: Oppose. The two are distinct topics and have different issues. The difference between the two is a constant, but that does not mean the articles should be merged. Glrx (talk) 18:54, 12 May 2017 (UTC)

text: Oppose.  If this article was already small, then it might make sense to merge.  Though I suspect that much of this article is comparisons to synchronous logic, which might be simplified or reduced linking to that article. Synchronous logic is not just any logic that isn't the subject of this article, but has its own design criteria and methodology. All of that should go into that article. (I didn't look to see if it is there.) But also the subject of this article is not just anything which doesn't satisfy synchronous logic. That leaves some room for quasi-synchronous logic.

thread_title:  External links modified 

message: While a UART is not normally (or ever, as far as I know) built with asynchronous logic, the complete system of sender and receiver, using asynchronous communication, should qualify as an asynchronous circuit.  Not completely asynchronous, though, as the usual design synchronizes at the beginning of each character, depending on the individual clocks not being so far off.  Some Ethernet systems depend on the receiver synchronizing (phase-locking) to the transmitter.  Others, I believe starting with gigabit, choose one end of a link, and use that as the clock source for both directions. (That is, the system really is synchronous.) It would seem that some of this might go into this article. Gah4 (talk) 21:47, 11 October 2019 (UTC)
