[edit] Suggest 1 possible wiki link and 2 possible backlinks for "arithmetic and logical unit"

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:

• Can link carry-out: ...es, which can be used to indicate cases such as carry-in or [[Take-out|carry-out]], overflow, or other statuses....

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

• In Combinatorial logic, can backlink arithmetic logic unit: ...natorial and sequential logic. For example, the part of an [[arithmetic and logical unit|arithmetic logic unit]], or [[ALU]], that does mathematical calculations is made fr...

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

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)

[edit] Difference between ALU and core

There is an emergence of multicore processors. So what's the difference between ALU and core?

An ALU is an execution unit, directed to its chores by the control unit; both those units are part of the CPU core. Today, a core may often contain several ALUs as well as other types of execution units. --Wernher 03:18, 30 October 2005 (UTC)

the ALU is a basic building block of a CPU or CORE.
its the same relationship as the AND gate to the Half Adder as ALU is is to CPU/CORE
the ALU is a very complex and important block that needs more info on it on this page. it is a small part of a cpu core but its prob the most complex part and critical part to understanding how a cpu works. Eadthem (talk) 03:55, 28 December 2007 (UTC)

[edit] History

Few issues... First, von Neumann didn't design ENIAC, though he certainly knew of it and was influenced by its design. Mauchly, Eckert, Brainerd, and Pender are the big names usually associated with ENIAC's design and manufacture. Second, it's pretty debatable whether the ALU was originally suggested for EDVAC or not. It would be good to try to find the first usage of the term and if that cannot be found, you can probably at least mention earlier devices that were more or less ALUs with I/O devices (like the IBM series of tube multipliers, adders, etc with punch card I/O). -- uberpenguin 15:48, 3 January 2006 (UTC)

[edit] Division/Multiplication

Is it not true that division/multiplication can be done by bitwise shifting and addition/subtraction?—Preceding unsigned comment added by 60.240.107.52 (talk • contribs)
