Well by some of us it is knowledge , digit Is davinchi processor from TI
You need to back that claim up with some actual facts
, man. I've been searching the web for an hour now, and I have yet to find any actual evidence of that. The ONLY direct link between DIGIC 5 and Texas Instruments DaVinci specifically is a hypertext link
to the Texas Instruments DaVinci wiki page from the DIGIC wiki page's References
. The only references to ARM on that wiki page are DIGIC II and III, so it stands to reason that if DaVinci ARM-only processors are related, that they would be related to those two versions of DIGIC. The only other source of information is someone on DPReview
claiming that the ARM subprocessor embedded within DIGIC 5
"was probably a Texas Instruments DaVinci series of application processors". According to Tech-On's dissection of a DIGIC 4
, it does appear to be a package-on-package, however it appears there is only a DIGIC 4 and the Samsung memory...if there is an ARM processor embedded in the DIGIC 4 die, they don't say.
As for ARM, that is simply the general purpose sub-processor contained within some DIGIC packages, however there is also a DSP for high speed image processing. TI may have made or designed the ARM processor (I still have yet to find any actual evidence of that, but it stands to reason Canon would outsource such design to a third party that has more experience with GENERAL logic processing units), but historically Canon designs and manufactures their own DSP/image processors
according to all of the actual evidence I've been able to find thus far. The ARM processor is also only a confirmed
part of DIGIC II and III, I have yet to find any direct evidence that DIGIC 4 or 5 also contain an ARM processor or if so whether it was designed by TI.
Much as I'm hesitant to support (albeit partially) Mikael's contention about the Digic 5+ chip, chipworks believe it to be designed jointly by Canon and TI, and fabricated by UMC.
believe.. i thought that belongs in church?
so it´s not common knowledge... it´s common believe?
Yes many belives a lot here and I keep to facts , digit is not a canon processor
Here's the problem...what you just posted there, and all of your previous posts? Those are not
...they are what we call an anecdote
. You are making anecdotal proclamations in the total absence of fact
. If you wish to make a claim, and intend for that claim to be accepted "as fact", you need to back that claim up with some external references that allow others to VERIFY your claims as fact. Simply stating that what you say
is plain and simply fact does not actually make it a fact.
Based on the information I've been able to find, information which I have also linked within my posts, The Suede is at the very least being very misleading about DIGIC being designed by a third party. He makes it sound as though Canon had no hand in the design, and that it was entirely designed and manufactured by third parties. I've found a single reference from Chipworks that the DIGIC 5 (and quite specifically JUST the DIGIC 5, not the DIGIC 5+ or other variants) was jointly designed by Canon and TI. I can't figure out exactly why they make that claim, and if the DIGIC 5 includes an ARM processor like the DIGIC II and III, then it is entirely possible that TI is only responsible for the ARM processor embedded within the rest of DIGIC 5's logic gates. There does not seem to be any information at all that indicates DIGIC 5 of any variant is specifically a DaVinci DSP either. As far as I can tell, the reason Wikipedia linked the TI DaVinci page was the same reason they linked the Nikon EXPEED page...DaVinci, EXPEED, and DIGIC are all digital camera DSP's, some of which have a general purpose ARM processor embedded.
I have yet to find any concrete evidence that it was manufactured by a third party, however I wouldn't state it as plainly impossible at this point (Chipworks seems to think there are some design markers that indicate UMC
, but that is far from definitive enough to claim as undeniable fact...UMC devices usually have their logo, "UMC" encapsulated in an angular oval or the little wireframe globe symbol). All of the actual evidence indicates that Canon does indeed design and manufacture their own image processors in general. There are also only two verified instances (that I have yet to find) in the past where Canon has included an ARM processor embedded in the same die or package as the DIGIC processor...in the DIGIC II and III. Here's that same link
, in case you want to verify.
