Data-HexConverter

The Data::HexConverter module provides functions to convert between hex strings and binary data.

This modules use SIMD instructions to perform high speed conversions.

Any machine this module is built on should have SSE3 and AVX2 SIMD instructions available.

This is most likely the case for any machine built in the last 10 years that has i5 or later (compatible) processors.

Some machines may have the AVX 512 instruction set, this module will those if available.


CPU Features

Determine if you CPU supports AVX 512 instructions:

On a local VM:

  $ gcc -O3 -Wall -Wextra -mavx512bw -mavx512vl -o probe_isa probe_isa.c
 
  $  ./probe_isa
  FEATURES: sse2 avx avx2

On a local server that supports AVX 512:

  $ gcc -O3 -Wall -Wextra -mavx512bw -mavx512vl -o probe_isa probe_isa.c

  $ ./probe_isa
  FEATURES: sse2 avx avx2 avx512bw avx512vl

INSTALLATION

To install this module on a standard machine, run the following commands:

	perl Makefile.PL
	make
	make test
	make install

If the machine has avx512 support:

HEXSIMD_ENABLE_AVX512=1 perl Makefile.PL
	make
	make test
	make install

Verify Implementation Used

Local VM without AVX 512:

  $  PERL5LIB=./lib LD_LIBRARY_PATH=$LD_LIBRARY_PATH:./blib/arch/auto/Data/HexConverter perl isa.pl
  Hex to Binary Implementation:
  avx2
  Binary to Hex Implementation:
  avx2

Local Server with AVX 512:

  $  PERL5LIB=./lib LD_LIBRARY_PATH=$LD_LIBRARY_PATH:./blib/arch/auto/Data/HexConverter perl isa.pl
  Hex to Binary Implementation:
  avx512bw
  Binary to Hex Implementation:
  avx512bw
