[sac-user] SAC2C: Cache Simulation

[Clemens Grelck]

> I think the cache simulator is Clemens' toy?

Hi all,

Indeed the cache simulator is my tool or better say I supervised the
work back in the late nineties.

The most exhaustive description is what you get with sac2c -h.
That also explains all the features supported with respect to
cache architectures. Anything beyond requires extension of the
simulator.

There is no further documentation of the cache simulator other than
the source code.
