A couple of years ago, Ola Jeppsson started working on a 1024-core simulator as part of his Master’s Thesis at Chalmer’s University in Sweden. (advisor, Sally McKee). He picked up the project again in 2016 as part of the validation process of the 1024-core Epiphany-V. Debugging with the simulator is an order of magnitude easier than with hardware, so you should…

The box on the top is Patrick’s Parallella work, the box on the bottom in the picture is his old digital power amplifier. I had the pleasure of meeting Patrick at the last Parallella…
