DummyLSU as a FU #635

Closed tilk closed 6 months ago

tilk commented 6 months ago

Oops, I did it again. DummyLSU is now smaller, faster, and a FU. As this LSU is still dumb, FifoRS is used to maintain the instruction ordering. Still, having an actual RS for LSU allows for more latency hiding for memory requests.

Depends on #634. Fixes #591.

TODO:

[x] Move DummyLSU to fu directory.
[x] Fix tests.
