  • Any NEON instructions can be dual issued with vector long multiply accumulate (SMLAL) on Cortex A53 or A55?
    Anyone know if this is possible? I've tried several instruction mixes: A53 A55 smlal.int8 & 64bit load (ld1) 0.97 1.72 instructions/cycle smlal.int8 & 64bit dup 0.97 0.96 smlal.int8 & 64bit or...
