That seems more like unprovable pseudo-science at this stage of mankind's knowledge. Where's the hard data backing up these claims of the soul's existence and unlimited "capacity"? It certainly may well exist, but until it can be detected, measured and it's properties well understood, it can't be used in the context of being the driving force behind the brain's capabilities. One must use hard, empirical data to back up one's claims - not speculation bordering on fantasy, when proving/disproving a scientific theory.

The SpiNNaker team is forgetting one important things about the human brain. The Soul... The core of the brain is the human Soul. Although, the brain has limited memory capacity, the soul has unlimited capacity. Man would never be able to understand the complexities of the human brain and all its functions, unless man humbles himself before the only ONE who truly knows the brain in and out, because HE invented it. GOD.

There used to be the CRIS chips from Axis, but these seem to be discontinued. It just strikes me that when you need a processor like an ARM (or MIPS, PPC, Coldfire, etc.) with more memory than you can get with a microcontroller, then you are going to need the CPU, DRAM of some sort, and Flash of some sort. If someone were to put all these modules inside one package, it would save a lot of effort and board space for many users. If you find out about any suppliers that make such packages - and are happy to sell to small companies - I'm sure it would make an interesting article.

You are telling me that there is a market need; Professor Furber is telling me it is physically possible. Therefore, market economics dictates that someone will go to the venture capital community (or to a corporate investor such as Samsung, Qualcomm or even ARM) and raise capital on the strength of the idea. Indeed it is likely that someone already did and is being stealthy. We will try to find them for you.

There is just one tiny little hinder to designing my own ARM device - money! There are lots of SoC devices available from different manufacturers, with all sorts of different cores. But there are not many that have a decent amount of memory in the same package. The idea of a single package containing a decent CPU (single or multi-core) and plenty of memory is very appealing - it would be smaller and easier to use than separate chips.

@David Brown I suspect the answer is that you cannot. Even if you approached Professor Furber with a deal -- say the donation of a shiny new building for the University of Manchester to be called the Brown-Furber School of IT -- you might find that Professor Furber's hands are tied by the licensing terms he agreed with ARM. But there is nothing to stop you taking a license and designing your own many-core ARM device. Professor Furber has shown that 18 cores plus loads of memory is possible in a 130-micron process. What could you achieve at 32/28-nm or 22/20-nm?

The big question is, where can we buy these chips? I can think of a lot of applications for a small package with multiple ARM cores and plenty of on-board memory...

Think of human memory as an analogue IIR filter, rather than a digital FIR, and you get roughly the right idea. Human memory is limited, but (for most people) rather large. It is also very efficient in storage - it remembers things in relation to other things, rather than "raw data". And your recall mechanism is mixed in with your imagination - if you can't remember details, your brain can make them up.

100 billion/1 million*1%=1000 neurons per processor.

1 neuron = 1 ARM processor? I would assume neuron to be a routing/repeating entity than a thinking entity(?).
