Hi, this might be the wrong forum, apologies if so!I am working on porting image filters implemented using ARM Neon vector extension to ARM Cortex-M55 using Helium vector extension. One instruction that has been very widely used in our Neon implementation is vext. This instruction allows simple implementation of sliding windows and kernels. However, I cannot find anything similar in the Helium instructions. Does anyone know how I could efficiently replace vext with something from Helium? I was thinking there might be a predicate instruction, but I haven't found anything yet. Thanks!
