Breadboarding with a 144-core processor

At the center of that green PCB is a tiny little processor with way too many cores. It’s the GA144 which was taken for a test-drive on a breadboard by [Andrew Back]. We saw a multi-core Kickstarter project last month. This will cost a lot less and get you more than twice the number of cores. But as was mentioned in the comments on that post, the drawback is the programming language. This chip’s IDE uses Forth.

There is a dev board available, but [Andrew] went instead with a QFN-to-Through-Hole adapter board which he hand soldered. Once he has access to the pins the chip can be programmed with an FTDI adapter which is compatible with the 1.8V logic levels. The provided Forth IDE (arrayForth) is a Windows only program but it does run under Wine. We followed the project through to see him twiddling I/O pins. But we still have trouble thinking of applications for it. In a world of complex and inexpensive FPGA chips, what would you use this type of processor for?
