Does he mention the clock speed of this thing? Wonder what the size comparison would be if it was built on say a 20nm scale?

- voycey 10y agoOh found it on the Reg article - 20khz (0.02Mips)
- ychompinator 10y agoI think he mentioned somewhere that he had it running at 50 khz now. http://megaprocessor.com/GBU_speed.html http://megaprocessor.com/GBU_speed.html - speed page!
- vardump 10y ago0.02 MIPS for real? I'd expect about 0.005 MIPS from a design like that. Many early CPUs took multiple clock cycles per instruction, anywhere between 2 and 10+. So all instructions are executed in a single clock cycle?
- vardump 10y agoTo add, here's a nice table of Meaningless Instructions Per Second for different CPUs: https://en.wikipedia.org/wiki/Instructions_per_second#Timeline_of_instructions_per_second https://en.wikipedia.org/wiki/Instructions_per_second#Timeli... It's pretty representative of 8 bit CPU true performance.
- cottsak 10y agoIn the video he has it running just over 1Hz so the flashing of the LEDs can be seen with the naked eye. As he brings it up to about 8KHz everything blurs and goes solid (as you'd expect).
