I don't see any advantage on going to MIPS: it's a very niche architecture.

The only good thing that I see is that Imagination continue to improve it, and presents new micro-architectures. That means that the architecture is still alive.

However, I don't know how long they can continue against ARM (which is their primary competitor) and x86.

Such irony in that statement.
So is 68K, so is PPC, so once was arm in the low power gap.
MIPS apparently plans to start in the wearable tech niche. And then from there?
I find it appealing in it's relation to RISC and 68k.
I have two of their dev boards, but no time recently to do much with them.

As also Cavium seems to invest in ARM instead of MIPS, I doubt MIPS can have better future than Power Architecture.

So, IMO, PowerArchitecture or x64 are the sane options today.
(PowerArchitecture, because all our current NG flavours run on it and it also is available also for Classic systems etc.)

Our systems are starting to use e5500 cores, and after that there's still the e6500 to explore ( if "NGCore" or some IBMLowEndPowerSoC never come ). During that period (10+years) we can try to master multicore & 64bit etc. before ISA switch.

(noticed that intel has now xeon with integrated FPGA ... silly dreamers can start to drool after AAAAHombreCaipirinha SoC ?)

xeon? yeah that'll be cheap affordable hardware.

True, but we were talking about a possible replacement for PowerPCs, and IMO doesn't make sense to seek for another niche architecture. That's all.

There are many competitors for wearables, and IoT too. I don't know if MIPS/Imagination has the (economic) power to compete.

Honestly I fail to see the relationship between 68Ks and MIPS. For me they are one the nemesis of the other.

I think the same.

Power = POWER I believe, but that's only for servers, and costs A LOT.

Nothing interesting here.

Consider that fully supporting 64-bits (I mean: both o.s. and applications can handle >4GB of memory without tricks like the infamous "bank switching") already requires a big effort, similar to an ISA switch.

Only some of them.

I think that such systems have already enough horse power to emulate AAA or Hombre without requiring an FPGA.

Isn't that a bit slow? I thought millions of instructions per second is considered rather basic these days and BIPS, TIPS or even GIPS would be more acceptable.

>I think that such systems have already enough horse power to emulate AAA or Hombre without requiring an FPGA.

Sure. That's why I added one A etc...

Freescale price list (does not include VAT etc):

Observation... they do not yet list any layerscape mid or high performance parts. Only some ARM based on the low end.

And that is a very good point. ARM is acceptible to me as well. MIPS sounds fun as well IF it goes anywhere.

That T1022/T1042/T2081 triple-design I keep bringing up is starting to look more and more like the only useful design.

@olegil

I have been toying around with how to place all the stuff.

Some things:
-so far I have dropped my very old idea of CPU+GPUetc that are plugged on "passive" bus-board
-nano-ITX
--looks like plenty of space to fit everything (2...4 PCIe/mPCIe, 0...2 SATA etc.)
--but non-standard (to ATX or mini-ITX) PCIe slot locations are not nice
--how to arrange suitable cases ... could this be on 5'25" drive bay
--there are some examples how nano-ITX boards can house one PCIe, though (why not two)
--for better placing, for various GPU options, ribbon risers or busboards can be used
-mini-ITX
--everything+more fits on it
--Full size DIMM fits on it (compensates the price of larger board???)
--can simply use normal ATX + ITX cases
--simple to have space for MXM GPU if needed (just not yet sure if they bring up the system price too much)
--mini-ITX motherboard in mini-DTX capable case gives room for large GPU on standard located PCIe slot
--would it be sane to fill the "empty/free" space with traces&connectors&sockets for Geeks (Arduino shields compatible even???) just to leave that unpopulated by components untill support exist
--also this size could easily fit PCIe to multiPCIe bridge and existing & supported SATA and audio chip. But I'm afraid it starts to become complex. Rather see minimalistic low end with open/free expansion slots.
-mini-DTX
--if large GPU is on upper slot, not much fit in lowest slot
--if large GPU is on lower slot, the case needs to be larger than tight mini-DTX case (flex-ATX case?)
--I rather use mini-ITX with one standard and one non-standard slot location

And I still think DIU might be usefull. (before prototype it should be tested on T10x2RDB)
(T2081 does not have it, but is the T1042-T2081 compatible configuration compatible with DIU. FFS)

And I'm open for 3-4xPCIe/mPCIe + 1...2SATA (not T2081 compatible?) and for 2xPCIe configuration. (initially it anyway must be booted from SD card before other drivers are done)

+++++++++
It would be very nice to have design open to use T1014/T1012/T1022/T1042/T2081.
If we get multicore supported, then T1042 or even T2081 would be worthwhile release.
Otherwise T1022 is already overkill for Amiga niche, even if it's bare minimum for Linux geek.

@KimmoK

FFS? For ****s sake?

T1040 DIU shares pins with the QE, which was the only place except IFC and PCIe you could have put some sound signals. QE pins are also GPIO, two of them are I2C

T2081 lacks both DIU and QE, so there you simply get an extra I2C and some GPIO if you can be bothered to wire that. I don't think it's useful.

The serdes configurations are similar enough, but 2081 lacks SATA. I am THINKING it would be best set up as two x4 PCIe (2081 0xAA, 10x2 0x00), with a SB chip providing the single lane PCIe ports needed.

@KimmoK

To get enough USB for audio you need some extra chips, a SB will provide you with USB and audio so that's a simpler solution. I replied in your SB option thread

From the above URL,"The company still offers several dozen Power-based QorIQ and QorIQ Qonverge processors, but ARM seems to be the future direction here."

Yep, everybody reading freescale material get that feeling.

PowerArchitecture is mentioned with future new Layerscape chips etc. but that's all.

Someone might think "ARM" is just good PR.
Realists predict that Freescale can not maintain performance lead with PPC vs ARM.

Time will tell. I could bet that after next 10 years there is no more PPC in Freescale QorIQ chips. And few years after that perhaps no PPC cores in high end either.
