there I am trying to do some performance improvement about libfaac/libx264 encoder using ffmpeg and neon.seems successfully开发者_Python百科 compiled ffmpeg with neon support,and video encode performa
If I understand it correctly, because ARM instructions are 32 bits long they can only hold so many bits of immediate value. What I\'m trying to do is vmov.f32 s0, #0.0, and I get \"immediate out of ra
I\'m trying to optimize an image format conversion on iOS using the NEON vector instruction set. I assumed this would map well to that because it processes a bunch of similar data.
I am developing a native library for Android where I use ARM assembly optimizations and multithreading in order to get maximum performance on the dual-core ARM chipset MSM8660. While doing some measur
I\'m trying to build a library for a Cortex A9 ARM processor(an OMAP4 to be more specific) and I\'m in a little bit of confusion regarding which\\when to use NEON vs VFP in the context of floating poi
I\'m having some trouble figuring out the NEON equivalence of a couple of Intel SSE operations. It seems that NEON is not capable to handle an entire Q register at once(128 bit value data type). I hav
Does NEON support aliasing of the vector data types with their scalar components? E.g.(开发者_如何转开发Intel SSE)
I\'m sure people do this all the time, but I\'m having a hard time here. I\'m passing an array of floats to a JNI function, but t开发者_如何学JAVAhen I\'m intended to use NEON SIMD capabilities of ARM
Im rather new to assembly and although the arm information center is often helpful sometimes the instructions can be a little confusing to a newbie. Basically what I need to do is sum 4 float values i
I think this a silly problem but i tried for a day to resolve this with not luck, so here is. i have register of four vectors (float32x4), and i want to make some process on some of them and the othe
