| Im not a technical guy but theoretically could the natami board be used to create a handheld portable gaming/computer device.The board doesen't generate much heat if i remember.The guy on the fpgaarcade site has a mockup of his board with an lcd screen attached.I don't expect team natami to do this, I'm just wondering.Slightly unrelated but here's a vid of a homemade dreamcast portabl EXTERNAL LINK

| There is even a N64 handheld, this had been done by molding the circuits.

And a gamecube one.The natami board is small enough at least so who knows.

| Yes, the board is small enough and also draws little power enough. I think it will be only a matter of time until someone like the people on EXTERNAL LINK makes a Natami portable. But don't expect us to make a portable. :-)

| Jacob in theory a lot is a option, in reality who is gonna do this?

| Not I. But it can't be much harder than doing a N64 portable.

| I think a portable Natami is achievable with some tinkering.
How portable and how refined I just won't know until I have one in my hands.Cheers,
Andre

| 1 enormous IC (2.5*2.5 inches), 68070 with 64 bit S-AGA in a 22 NM ASIC @ 1.071 GHz, with no L1 or L2 cache, just 1 Gig of RAM in CPU and no other RAM than 128 GB Flash internal for storage and 2 micro SD flash sockets*, .... in a "new iPad" shell...... With new and unheard of "insta-boot" tech!!!! Don't wake me up, or wake "when it's done".... :-))))) * HDMI/DVI/VGA/USB2/RCA(aud/vid)

| Thierry the figures you just said are again unrealistic, i hope you sleep well then.

| Marcel, the 128 GB of flash storage is on other ICs. Oh, yes, 2.5 inches square can't support 8 billion gates + the 68070. 3*3 then? EXTERNAL LINK
'The transistor count of a device is the number of transistors in the device. Transistor count is the most common measure of integrated circuit complexity. According to Moore's Law, the transistor count of the integrated circuits doubles every two years. On most modern microprocessors, the majority of transistors are contained in caches. As of 2012, the highest transistor count in a commercially available CPU is over 2.5 billion transistors, in Intel's 10-core Xeon Westmere-EX. Xilinx currently holds the "world-record" for an FPGA containing 6.8 billion transistors.'

| The Bigger the die exponentially increases chances of a defect. (dead part)
If freescale gets wind of it the team might have a lawsuit on their hands.So production technical it's more interresting the keep the mayor components on different die's this also allows independent development.
Which means a increase in the update cycle, because they move independant of each other.(this is the only reason i like the FPGA) Moore's law is decrepit, this is due to the increase in wire resistance, Cost of R&D, Materials, & Equipment. So the problem isn't the transistor count it's connecting them all.
That is why the Development is moving towards layering of gates. BTW link to the correct page when quoting. ;)
http://en.wikipedia.org/wiki/Moore's_law
Read the part of moore's second law, Rock's law. Thierry your talk about transistor count makes me wonder if your a true Amigan.
As always it not about transistor count, it is about what you do with it!

Why do I talk about such a high transistor count?It's because I was wondering if virtually EVERY COMPONENT of the computer could be squeezed into one IC. All the RAM is in the CPU, there are no other RAM chips except for flash RAM storage for when it's turned off. The ROM is in there and no L1 or L2 or L3 cache whatsoever is present, because all the RAM is a part of the CPU.

| There are such CPUs, integrated with the RAM, but they are apparently very slow compared to normal CPUs. But if you by IC mean the ceramic or plastic enclosure, why not... that should be possible.

This is possible but not a really great idea. The production processes for logic chips and RAM differ a lot. If you design a process for producing RAM and logic on the same chip, you will get slow logic and slow RAM because you will have to settle for the lowest common denominator.

| Actually there is a normal DRAM with a slow CPU in it now.

| Thierry said it all on one Die this would not be acceptable for Chipset, CPU, ROM and RAM ROM, ROM is Read Only Memory, This is where the bootstrap is stored, This needs to be external. (Kickstart upgrades, optional but still sound advice) RAM, This may vary in need and requirements from user to user. (Best to keep external, no need to reinvent the wheel for our own usage) CPU, This is a decoupled part with it's own development cycle this could be squized in the same IC as the chipset but this would eliminate a upgrade path. Chipset, Same as above, but with this difference development and market get totaly decoupled because CPU and chipset need to wait on each other. Decoupling development, decreases development time, smaller groups on smaller projects. Besides that Jacob, are you proposing a suboptimal solution here?

| I didn't know that the various components were like trying to put too many different ingredients in a soup, say, and thereby ruining it.
