--- Comment #23 from Cesar Strauss <cestrauss at gmail.com> ---
I suggest also comparing hazard avoidance performance in a Tomasulo-based
architecture.

By the Tomasulo transformation, I guess, it should be equivalent to the
Augmented 6600 Scoreboard
(https://libre-soc.org/3d_gpu/architecture/tomasulo_transformation/)

I found interesting examples of multi-issue Tomasulo architectures at
https://www.brown.edu/Departments/Engineering/Courses/En164/Tomasulo_10.pdf
(I just added it to the Resource page).

It has some execution traces showing hazard avoidance. It also shows how
register renaming occurs implicitly in the reservation stations (in the second
example, it happens in the reorder buffer instead).
