Once the ROM is in PSRAM, with our own probably faster QPI controller, we might have really low latency and might be able to go below 200ns on a constant basis.
Patch the PI configuration word to lower values.
Write a stress test ROM.
Update:
Not going for a custom QSPI controller. But by doing prefetching, data could be served quite fast.
A stress test ROM is still something we should do.
How fast can we go?
