No Voodoo Rush with CL chip.

Later, the company was one of three companies to provide a VGA-controller for the 3dfx Voodoo Rush 3D-accelerator card. The chips Cirrus Logic used were derivatives of the Laguna family, with model numbers GD5645 and GD5646. The Voodoo Rush card combined two separate graphics controller chips for legacy-VGA (2D) and 3D functionality. Both chips shared the same framebuffer memory. However, the Voodoo Rush boards were a disappointment because the 2D chip was inferior to many cards of the time, and its 3D was slower than that of the older and separate Voodoo Graphics board.

I am a collector of 3dfx related hardware and as such know a significant amount about 3dfx hardware. I have come across a lot of Voodoo Rush cards but never, never have I seen a Voodoo Rush with a Cirrus Logic chip. To the best of my knowledge, only 2D chips from Alliance Semiconductor and Macronix were used.

I suggest the above quote is removed from the article. NitroX infinity (talk) 23:42, 8 February 2009 (UTC)

Source of company name

I was told that Mr. Patil's Daughter came up with the name Cirrus Logic. She was a child in school at the time and they were studying clouds. The Cirrus Cloud was the "highest cloud" she said, and the name stuck.

FWIW.

Blacklisted Links Found on the Main Page

Cyberbot II has detected that page contains external links that have either been globally or locally blacklisted. Links tend to be blacklisted because they have a history of being spammed, or are highly innappropriate for Wikipedia. This, however, doesn't necessarily mean it's spam, or not a good link. If the link is a good link, you may wish to request whitelisting by going to the request page for whitelisting. If you feel the link being caught by the blacklist is a false positive, or no longer needed on the blacklist, you may request the regex be removed or altered at the blacklist request page. If the link is blacklisted globally and you feel the above applies you may request to whitelist it using the before mentioned request page, or request it's removal, or alteration, at the request page on meta. When requesting whitelisting, be sure to supply the link to be whitelisted and wrap the link in nowiki tags. The whitelisting process can take its time so once a request has been filled out, you may set the invisible parameter on the tag to true. Please be aware that the bot will replace removed tags, and will remove misplaced tags regularly.

 Resolved This issue has been resolved, and I have therefore removed the tag, if not already done. No further action is necessary.—cyberbot II ^Notify_Online 00:15, 4 March 2014 (UTC)

Did they or didn't they manufacture/sell graphics cards?

Notes about "75%" statement

I removed the following statement from the article: "Cirrus' revenue is dominated at over 75 % by just one major customer." The referenced material does not say that (https://s21.q4cdn.com/307563939/files/doc_financials/2021/q4/Cirrus-Logic-Investor-April-2021-Presentation_FINAL-(1).pdf), it says "In Q4 FY21, our largest customer represented 76% total revenue". The statement in the article implies this single customer is responsible for over 3/4's of their revenue on an ongoing basis, while the financial statement only declares that for a single quarter. With the single data point, there's no way to tell if it's an anomaly or not. smnc (talk) 16:30, 24 January 2022 (UTC)
