OMAP Acronym

OMAP : Open Multi Applications Platform

Why no mention of the meaning of the OMAP Acronym. I think it is "Open Media Applications Platform." --Ralph walden 19:12, 13 October 2006 (UTC)[reply]

I don't believe it is an acroynm --JadonK (talk) 06:24, 1 April 2008 (UTC)[reply]

The article now says that OMAP stands for "Open Media Applications Platform." As far as I know, that is both true and verifiable. (...in which case, it does seem to be an acroynm). --Mike Schwartz (talk) 20:07, 11 May 2010 (UTC)[reply]

How does it stand for "Open MAP" if the article says it's proprietary?? 136.176.104.153 (talk) 22:11, 15 November 2008 (UTC)[reply]

IMHO that is a good question. That is, how can something "call itself" by an acronym in which the first letter stands for "open", and at the same time, be proprietary, or be "part of" a product [a microprocessor] that is called "proprietary" in the very same sentence.

The ANSWER (as far as I know), is as follows: I think the thing that is proprietary, is the chip itself, and perhaps also some firmware or software that comes with it, or (at least) goes with it. That is, the firmware or software that is proprietary, is either bundled with the chip, by the hardware manufacturer, or (at least) is designed to work closely with the chip [hardware]; and, the firmware or software that is proprietary, is probably covered by some kind of restrictive license agreements that are far less "open-ended" than (say) the GNU GPL.

OK, so far that (imho) takes care of the part [of the question] about the word "proprietary". Now, for the other part [of the question] -- the part about the word "open". How is the word "open" appropriate, here?

I may be going out on a limb, here, because this is just my guess. I think that the OMAP ("Open Media Applications Platform") is seen as a "platform" that gives anyone -- individuals, or even Independent software vendors (ISV's) who might be in business to make a profit -- the opportunity to write applications that run on that platform [that is, on OMAP]. So, the individuals and ISVs might have very limited licenses, when seen from the standpoint of their rights -- (or lack thereof) -- to compete with the sellers or providers of the parts that are proprietary -- that is, the chip itself, and the firmware or software that comes with it, or goes with it (as discussed above); but, they (individuals and ISVs) do have a pretty OPEN opportunity to compete with each other, in terms of applications that run on top of the underlying platform, and/or to write such applications for their own use, perhaps without any intention of distributing them externally.

I could be wrong here, but I think it is more likely that this explanation is correct, but is (perhaps) just a little more nuanced than what we can rely on to be automatically obvious to the reader, upon seeing a little "four letter long acronym" like OMAP ("Open Media Applications Platform").

Finally, does this [wanna-be] "answer" belong here (on the "Talk:" page), or in the article? I don't know, but my first guess is that it belongs here. (plus, maybe some other places, like perhaps in a glossy brochure -- [or a web page!] -- provided by Texas Instruments). Then, after that, if anyone disagrees, and thinks that this answer needs to be included in the article, -- or if they have any other comments, (etc.), then they can chime in, right here -- (on the "Talk:" page). --Mike Schwartz (talk) 20:50, 11 May 2010 (UTC)[reply]

omap 1510/5910

is it the same chip???

No, they're not the same chip, but they are very similar. There are slight differences in voltages and clock speeds, and some peripheral differences, such as 3 McBSPs on the 5910 and 2 on the 1510. Also the 1510 isn't recommended for new designs. -- DImfeld 00:47, 9 June 2006 (UTC)[reply]

OMAP5

It is not correct to call OMAP5910/OMAP5912 as "OMAP5". --JadonK (talk) 13:47, 2 March 2009 (UTC)[reply]

Image Signal Processors

There seems to be some confusion about an additional Image Signal Processor in the OMAP3 (and 4) family. At least for the omap3530, the also mentioned C64x DSP actually is the "High Performance Image, Video, Audio Operation (IVA2.2™) Accelerator Subsystem" (see its data sheet). I'm correcting the line for the omap3530, but I am not sure about the others. Sebsch (talk) 08:34, 1 February 2010 (UTC)[reply]

Actually, now I'm confused myself. Maybe there is one C64 as part of the IVA Subsystem and a second one for general purpose computing? I'd appreciate it if someone who knows for sure could clear this up. Sebsch (talk) 08:40, 1 February 2010 (UTC)[reply]

The IVA2.2 subsystem of OMAP3 consists of a C64x DSP megamodule, an EDMA3 instance, and a video acceleration sub-subsystem (or whatever) that consists of 2 or 3 special-purpose video en-/decoding accelerators (iME, iLF, and later iVLCD) and an ARM9 core to look after them. So it's not quite right to say the C64x DSP "is" IVA2.2, but rather it is part thereof. There is no second C64x DSP.

On OMAP4/5 (and also DM81xx and AM57xx) the situation has changed: they have IVA-HD consisting of a more elaborate set of six accelerators (iME3, iPE3, iLF3, MC3, CALC3, ECD3), two ARM9 cores, and a DMA controller. The subsystem is generally bootstrapped and supported from the "Ducati" dual-cortex-M3 subsystem (OMAP4, DM81xx) or its successor the "Benelli" dual-cortex-M4 subsystem (OMAP5, AM57xx).

The slightly pitiful "Tesla" C64T DSP on OMAP4/5 is not involved with video but closely associated with the Audio Back-End (ABE) subsystem. The Tesla DSP, which is a bit like a C64x DSP cut in half, has never existed outside the OMAP4/5 and support for it was dropped from v8 of the C6x compiler tools as being an "obsolete" core. In constrast, DM81xx have a C674x fixed/floating-point DSP available for general use, with some fast SRAM shared with IVA-HD (similar to how the C64x in IVA2.2 shares some RAM with the video accelerators), while AM57xx have one or two C66x DSPs, which are the latest DSP cores from the TMS320C6x family.

xmath (talk) 02:10, 28 December 2016 (UTC)[reply]

I just noticed there actually is interconnection between Tesla and IVA-HD on the OMAP4 (all three models), which I had overlooked previously. I'm more familiar with the OMAP5, and there no such connection exists. I have no idea what this interconnection may have been used for. My understanding is that Tesla is more intended for tasks such as low-power mp3 playback. xmath (talk) 02:28, 28 December 2016 (UTC)[reply]

what does "recently" mean?

At Texas_Instruments_OMAP#OMAP4 it says, "OMAP4 parts have recently been announced."

Where is the "as of" date? I think a statement like that is fine for some kind of newspaper or magazine, that usually has a date (month, day, and year!) right on the front cover (and -- often -- on [almost] every page). However, here, what is the reader supposed to do? -- dig through the "history", to see when the statement was added (by an editor) to the article?

Wouldn't it be better to include an approximate date? (something like, << "OMAP4 parts were announced in early 2010." >>)? Just a suggestion... --Mike Schwartz (talk) 20:59, 11 May 2010 (UTC)[reply]

I agree. I actually came to this page to learn a little about the history of OMAP, not just the facts. Let's all look around and see if we can find the relevant data. Guitarlesson (talk) 10:30, 15 June 2010 (UTC)[reply]

Sitara chips ?

No mention of the new sitara chips AM3715. Might not be labelled as OMAP but are pretty much functionally identical. TI seems to be using Sitara as a label for non-handset omap chips.

Alxxthegeek (talk) 00:57, 3 October 2010 (UTC)[reply]

In fact the AM37xx / DM37xx are the catalog versions of the OMAP36xx, rebranded under the Sitara or DaVinci labels depending on whether the IVA2.2 subsystem is enabled or not. You can actually still find some older references to "OMAP37xx" before it got rebranded to match the target market.

I recently gave an overview of the Sitara-brand SoCs and their relationship to the OMAPs and some DaVincis in this E2E post.

Cortex M3 also in 4430

Just like the OMAP 4470, the OMAP 4430 features 2 Cortex M3 cores. The proof can be found in this document http://focus.ti.com/pdfs/wtbu/OMAP4430_ES2.x_Public_TRM_vK.zip Look at chapter 7 (page 1095). — Preceding unsigned comment added by 84.85.7.81 (talk) 18:09, 5 June 2011 (UTC)[reply]

Motorola defy - omap 3630???

There are a lot of discussions wheter defy uses a 3610 or a 3630. So where is the reference to the statement, that it uses a 3630-800? — Preceding unsigned comment added by 84.185.9.2 (talk) 13:06, 1 August 2011 (UTC)[reply]

What does ISP mean?

ISP is (apparently) copy and pasted into this article without definition. Hcobb (talk) 21:59, 6 September 2012 (UTC)[reply]

I thought it was in-system programming, but checking the Ti website it turned out to be "Image Signal Processor". --Imroy (talk) 13:48, 7 September 2012 (UTC)[reply]

4428?

Best Buy has a new tablet called the Insignia Flex which uses a TI OMAP 4428. The numbers listed in this article don't include 4428 and the number 4428 is not in any of the linked pages that I checked either. What gives? Ken Arromdee (talk) 04:38, 30 December 2012 (UTC)[reply]

TI has no documentation of the existence of an OMAP4428. 「gu1dry」⊤ • ¢ 05:02, 30 December 2012 (UTC)[reply]
