> actually, i want to modify PLRU's API somewhat so you can have a sram of
> PLRU states and just one PLRU circuit rather than a bunch of dffs and PLRUs.
> the sram would need 1 clocked write port and one combinatorial read port
> (unless you want to wait an extra cycle), it would be external to PLRU.
