How to read the cycle counter results
(u.cccc-p ee xx rrr:ll)- u is the execution unit. Can be a (arm), n (neon) or v (VPf)
- cccc is the running cycle
- p is the pipeline used
- ee is the number of cycle required by the instruction
- xx is a lock not due to a register can be
- p0 wait for arm pipeline 0
- n0 wait for neon pipeline 0
- ls wait for load/store functional unit
- nq wait for NEON queue
- wb wait for WriteBack when a VMOV Arm reg, Neon reg occured
- wn wait for NEON empty queue to execute a VPf instruction
- rrr is the last register that cause a instruction stall
- ll is the number of "half-cycle" that the instruction have to wait for
