Talk:Programmable logic device

message: I will be adding a few items to this article from my book. 
I release these contributions to Wikipedia to the public domain.
I worked at Data I/O Corp on programmable logic from 1981 to 1997. I was fortunate to meet and work with the most of the pioneers in this field. I was on the development team for the ABEL programming language.
Feel free to correct my grammar and spelling.

thread_title: PLD and PAL history

message: The article Programmable logic array reads synonymously to this article. Does it make sense to merge both articles? If not, I'd be great if someone could differentiate both article from eath other by writing some words. --Abdull 10:54, 19 February 2007 (UTC)
thread_title:  PLA / Programmable Logic Array 

message: Hello, I'm working for the So-logic company, located in Vienna, Austria, www.so-logic.net. We have developed the FPGA Database application, www.so-logic.net/en/fpga/table/producers. It is the directory of all FPGA families that have ever existed on the market. It is free of charge and available to everyone. We would like to add the link to our database in the Wikipedia external links on this page. We didn't want to do it before discussing it with you. Thank you for your time. --Maja Gordic (talk) 14:59, 6 April 2010 (UTC)

message: Theoretically, there are 2^m possible Boolean functions of these m signals, but the structure of the ROM allows just 2^n of these functions to be produced at the output pins.
Huh?  This doesn't make sense to me.  2^n?  Seems to me that each of the outputs can produce any of the 2^m possible functions. 151.200.47.86 (talk) 03:47, 30 June 2010 (UTC)
replies: text: Yes, that version of this article was confusing. User:SMM SCL fixed it up and now it makes much more sense to me. --DavidCary (talk) 17:41, 4 July 2011 (UTC)
thread_title:  ROMs 

message: I hear that inside the 6502, 'The "Decode ROM" is named as a ROM in Hanson's block diagram, although it has wordline inputs and no address decoder. It is sometimes described as a PLA although it also lacks an AND plane. It is a structured layout of NOR gates with many common inputs'.
It's not exactly a PLA or PAL or a ROM or a CPLD or a FPGA -- is there a specific name for this kind of "single matrix of NOR gates" layout?

thread_title:  another type of PLD 

message: Hello. Is the FPOA = Field-programmable object array (by mathstar http://www.fpgacentral.com/pld-types/fpoa-field-programmable-object-array ) new type of PLD or it is just marketing name of some existing technique? `a5b (talk) 16:28, 17 November 2011 (UTC)
replies: text: Basically it seems they are taking the basic idea of a FPGA but rather than small flexible logic units they are using much bigger objects. This will presumablly offer improved performance at the tasks the device is designed for but reduce flexibility. Plugwash (talk) 12:50, 18 November 2011 (UTC)
thread_title:  [[FPOA]] / [[Field-programmable object array]] 

message: Simple programmable logic device is currently a stub; as all info that could be provided there is already in the main article on PLD's there is no rationale to expand this at SPLD. K7L (talk) 20:44, 17 September 2013 (UTC)
replies: text: I decided against the merger based on the amount of info the article now has. I was bold and removed the merge request.Calaka (talk) 07:14, 2 November 2015 (UTC)
thread_title:  Proposed merge with [[Simple programmable logic device]] 

message: Should PLS/FPLS integrated circuits be included under one of the existing sections (i.e. as a synonym or a varient), or should they be given their own section?
