UniSIMD-assembler download for Windows

Free download UniSIMD-assembler Windows app to run online win Wine in Ubuntu online, Fedora online or Debian online

This is the Windows app named UniSIMD-assembler whose latest release can be downloaded as UniSIMD-v1.0.0f.zip. It can be run online in the free hosting provider OnWorks for workstations.

Download and run online this app named UniSIMD-assembler with OnWorks for free.

Follow these instructions in order to run this app:

- 1. Downloaded this application in your PC.

- 2. Enter in our file manager https://www.onworks.net/myfiles.php?username=XXXXX with the username that you want.

- 3. Upload this application in such filemanager.

- 4. Start any OS OnWorks online emulator from this website, but better Windows online emulator.

- 5. From the OnWorks Windows OS you have just started, goto our file manager https://www.onworks.net/myfiles.php?username=XXXXX with the username that you want.

- 6. Download the application and install it.

- 7. Download Wine from your Linux distributions software repositories. Once installed, you can then double-click the app to run them with Wine. You can also try PlayOnLinux, a fancy interface over Wine that will help you install popular Windows programs and games.

Wine is a way to run Windows software on Linux, but with no Windows required. Wine is an open-source Windows compatibility layer that can run Windows programs directly on any Linux desktop. Essentially, Wine is trying to re-implement enough of Windows from scratch so that it can run all those Windows applications without actually needing Windows.




UniSIMD assembler is a high-level C/C++ macro assembler framework unified across
ARM, MIPS, POWER and x86 architectures. It establishes a subset of both BASE and
SIMD instruction sets with clearly defined common API, so that application logic
can be written and maintained in one place without code replication.
The assembler itself isn't a separate tool, but rather a collection of C/C++
header files, which applications need to include directly in order to use.

At present, Intel SSE/SSE2/SSE4 and AVX/AVX2/AVX-512 (32/64-bit x86 ISAs),
ARMv7 NEON/NEONv2, ARMv8 AArch32 and AArch64 NEON, SVE (32/64-bit ARM ISAs),
MIPS 32/64-bit r5/r6 MSA and POWER 32/64-bit VMX/VSX (little/big-endian ISAs)
are mostly implemented (/w horizontal reductions) although scalar improvements,
wider SIMD vectors with zeroing/merging predicates in 3/4-operand instructions
are planned as extensions to current 2/3-operand SPMD-driven vertical SIMD ISA.

See README file.


  • ======= UniSIMD core features =======

  • High-level SIMD registers/ops as singles, pairs and quads
  • SIMD-aligned backend structures with offsets/factors
  • Vector-length agnostic vertical SIMD ISA, configurable
  • Simultaneous scalar+128/256-bit+configurable SIMD ops
  • ISA reservation for fp16/fp128 (half/quad) SIMD ops
  • C/C++, Compute, SPMD on 4 major archs
  • Intel SSE/SSE2/SSE4 and AVX/AVX2/AVX-512
  • ARMv7 NEON/NEONv2, ARMv8 AArch32/AArch64 NEON, SVE
