NEON SIMD Register Diagram

Hello, I’m new to ARM architecture and was looking to get a better understanding of how it works. Most notably, the Cortex-A series and its DSP functionality. When looking through the NEON SIMD page on...
question about arm cortex-a9 neon optimization(4x4 matrix mul)

======================================= for matrix 4 by 4 multiplication, neon programming is slower than natural code with auto-vectorization option. (Xilinx Zynq 702 EVM board - cortex a9 with gcc complier...
Partial register dependency neon

I'm having trouble finding any informations on partial neon register dependencies. Take for example the following code: ld2 {v0.16b, v1.16b}[0], [x0] ld2 {v0.16b, v1.16b}[1], [x1] ld2 {v0.16b, v1...
