This comment has been moved here from Talk:arithmetic and logical unit.

An automated Wikipedia link suggester has some possible wiki link suggestions for the "arithmetic and logical unit" article:

Additionally, there are some other articles which may be able to linked to this one (also known as "backlinks"):

Rationale for renaming the article to "arithmetic logic unit"[edit]

The most common terms for ALU in the computer science literature seems to be "arithmetic logic unit" and "arithmetic-logic unit"; hence the recent renaming/move from "arithmetic and logical unit". Double redirects have been removed. --Wernher 16:09, 2 Apr 2005 (UTC)

74AS888 Information[edit]

{I am new to Wiki; Not sure where or how to ask so here goes.} I could not help but notice that the article includes a photo of the 74AS888 part from TI. I have been trying to find more information on this part with no success. Is anyone aware of where I might more info on this enigmatic part?

The 74AS888 chip (released circa 1982) is classified as "8-bit processor slices". It consists of an 8-bit ALU, 16x8 register file, support circuits for multi-cycle multiply/divide/normalize, data selectors, and a bit of glue logic. For more info, see TI's 1986 "LSI Logic Data Book". Lambtron (talk) 18:42, 21 July 2015 (UTC)
A copy of the 1986 "LSI Logic Data Book" that Lambtron mentioned is at and .
That includes the detailed technical data that a person would need to use that chip as part of a complete CPU, on page 2-293, as well as a "Bit-Slice Processor User's Guide" starting on p. 3-67, "Floating-Point System Design Using the 'AS888/'AS890" starting on p. 3-125, etc.
Which educational or commercial systems, if any, used one or more 74AS888 chips? --DavidCary (talk) 02:14, 21 November 2015 (UTC)

History of ALUs[edit]

I recently organized and expanded the history section. While doing that, I realized that it covers quite a lot of technical information that can only be understood after reading the technical sections below. It might be a bit unorthodox, but wouldn't it be logical to move the history section further down in the article, so as to make the history easier to understand?

No one has objected, so I've moved History below the tech sections. Lambtron (talk) 17:31, 22 July 2015 (UTC)
