There are 40 slots, so you might not get selected. But the open shuttle uses the same software and framework as chip ignite.
- mikewarot 5y agoI've had a chip design bouncing around in my head since the 1980s, now I can finally get it made. Thanks so much for posting this. The idea is simple... a grid of 4x4 LUTs, each geographic neighbor has 1 bit in, and 1 bit out, there are 16 states, each with 4 outputs. Turns out that this route-less FPGA can do some fairly amazing things, at least in theory. Now I intend to find out. The really old blog I had about it - https://bitgrid.blogspot.com/ https://bitgrid.blogspot.com/
- jecel 5y agoThere have been FPGAs in the past which used the logic blocks for routing, including the Xilinx 6200. I think that was also the case for the Atmel AT40K FPGAs, but could be remembering wrong. In fact, our project for the previous Google shuttle was an FPGA-like device which also routes data using logic cells. Here is an introduction to the idea: https://github.com/fiberhood/MorphleLogic/blob/main/README_MORPHLE_LOGIC.md https://github.com/fiberhood/MorphleLogic/blob/main/README_M... It worked in simulation and the chip is currently scheduled to be shipped to us on September 6. There were 2 or 3 projects that were more conventional FPGAs.
- mikewarot 5y agoThe Morphie blob looks like a special case of a 4x4LUT. I'd be interested to know how the chips work out.
- jecel 5y agoThere are some common features, but also differences that makes them a bit hard to compare directly. An academic project that takes yet another approach to this design space is: http://cba.mit.edu/projects/rala/ http://cba.mit.edu/projects/rala/
