  • Problem in understanding behaviour of GCC compiler (aarch64-none-elf-gcc) on Neon intrinsics for ARM cortex a53

    Hi,

    I am using IDE Xilinx SDK 2019.1 for my application and running it on ARM cortex a53  processor with Neon and floating point engine support available. I am working on a bare metal application.

    The problem I am facing is that, I am unable to understand…

  • compiler optimization options for ARMv8 GCC compiler on ARM cortex a53 (bare metal application)

    I am using ARMv8 GCC compiler(aarch64-none-elf-gcc) for my bare metal application on ARM cortex a53. I am using neon intrinsics with plain C in my code so I would like to ensure to use all optimization option available for this compiler.

    I tried -mfpu…

  • Optimization of Neon Intrinsics on ARM cortexa53

    I am using ARMv8 GCC compiler and I would like to optimize Neon Intrinsics code for better execution time performance. I have already tried loop unrolling and I am using look up table for the computation of log10. Any ideas?

    Here is the code:
