I am genuinely curious, I don't know much about instruction set design.
- Stevvo 6y agoI guess it's however many bytes the instruction occupys in L1 cache.
- saagarjha 6y agoThe pollution would be in the chip complexity.
- freeone3000 6y agoThis uses existing rounding modes with pre-set flags, so it costs 1 entry in the LUT and a small number of muxes, one per flag, assuming the worst case.
