Non-Temporal Writes in SIMD Instruction set

X-86 platform supports what they term as non-temporal writes. This just means stores from the registers to memory that do not influence the cache. They are purported to run faster. Are there similar instructions for the NEON where we can speed up a simple memory copy by writing directly to memory and bypassing the cache?
