KELLY 1

• Single, straightforward processor taking roughly 5 cycles per FLOP
• Memory system capable of providing two floating-point operands, and storing one, every 5 cycles
• Standard off-the-shelf optimising compiler
• Achieves close to peak performance on most problems
• Clock rate 500GHz, clock cycle time = (picoseconds)

  Requires logic gates and wiring with propagation delays around 0.1-0.2 ps (in this time light travels about ).
