The Mill CPU: The Belt Operand-Passing Model

HN points to the Mill talks as an excellent, deep look at an unconventional CPU design, especially in threads on registers and instruction sets.

The second talk in the Mill CPU series by Mill Computing, covering the Belt, the Mill's operand-passing model that replaces general registers. It explains the cost of register renaming in conventional wide CPUs and how the Belt reaches high instruction-level parallelism.
