i think you can fill the cache just by reading memory, as long as there is no address conflicts.
For the write i have no idea yet, but a simple bench with:
- sustained write
- sustained read
- mixed read / write
should give some useful informations.
The RAM for storing cached memory addresses also has a fast reset pin.
colourized schematics and SRAM datasheet:
