+
+More speed-up Q
+
+A. Is algorithm on HW fastpath?
+ ASM: reg cnt, int vs fp, on-chip ram, lzcnt, movemask
+ GPU: vec4, tess vs VS vs FS vs Blend vs Stencil, bandwidth
+
+B. Can we increase parallelism?
+ SoC SMP
+ SIMD
+ GPU
+ Cloud SMP
+
+C. Can we fix stalls?
+ Locks
+ Cache
+ Reg spill
+ Mem

+**1/** **@mike_acton** ^989001065893801984
+
+Mike Acton approximator:
+1. Can we not do this at all?
+2. Can we do this only once?
+3. Can we do this fewer times?
+4. Can we approximate the results so no one notices?
+5. Can we use a small lookup table?
+6. Can we use a small FIFO?
+6. Can we constrain the problem further?
