Below are the steps to get an ARM64 version of Ubuntu running in the QEMU emulator on Windows 10.

Install QEMU

Install for Windows from https://qemu.weilnetz.de/w64/ (I used qemu-w64-setup-20181211.exe)

Put C:\Program Files\qemu on your PATH, and run the below to check it's working (which will list out the CPUs the AArch64 emulator can emulate):

qemu-system-aarch64 -M virt -cpu help

Hello, Rust community!

My name is Hadrien and I am a software performance engineer in a particle physics lab. My daily job is to figure out ways to make scientific software use hardware more efficiently without sacrificing its correctness, primarily by adapting old-ish codebases to the changes that occured in the software and computing landscape since the days where they were designed:

• CPU clock rates and instruction-level parallelism stopped going up, so optimizing code is now more important.
• Multi-core CPUs went from an exotic niche to a cheap commodity, so parallelism is not optional anymore.
• Core counts grow faster than RAM prices go down, so multi-processing is not enough anymore.
• SIMD vectors become wider and wider, so vectorization is not a gimmick anymore.

AV1 coding scheme

• Arithmetic coding
  • multi-symbols (up to 16 values)
  • Coefficients coding: lv_map
  • CDF: Cumulative distribution function
    • CDF update (at the end of frame)
    • CDF update (adaptive per symbol)
• Image blocking
