arm v7-neon review - XoilacTV

Some Neon instructions act on scalars together with vectors. Instructions which use scalars specify a lane index to refer to a specific element in a register. For example, the instruction MUL V0.4S, V2.4S, V3.S[2] multiplies each of the four 32-bit elements in V2 by the 32-bit scalar value in lane.

Use github actions and Lakka repository to compile libretro cores for armv7-neon-hf devices. One possible use is update Lakka or Batocera cores. With each core there is an 'extra' folder that includes xml/dat files and some other files (inside the zip file).

Almost all ARMv7-based ("32-bit") Android devices support Neon, including all devices that shipped with API level 21 or later. The NDK enables Neon by default for both. If you target very old devices, you can filter out incompatible devices on the Google Play Console.
