AsciiMandelbrot - coded by Dino Papararo (Fl()sh) 29 apr 2018. Based  on  ascii
mandelbrot  app  taken  over  the web, it's the only one I know to use altivec
extensions, and for OS4 version GMP Library, to draw an ascii  mandelbrot  set
in  a  console  :-)  It  was  developed  on  QEMU/WinUAE  AmigaOS4 and MorphOS
(PowerMac g5 quad), mainly for testing and benchmarking purposes. I hope  this
can  be  useful  to  test in a fast way FPU and Altivec speed of PowerPc cpus.
AsciiMandelbrot is compiled with GCC v8/v9 to run under AmigaOS4 and  MorphOS.
It's  also  easily portable to other platforms like Linux, MAC OSX and Windows
OS. C Source code is included, to compile it just type MAKE in the shell :-)

Usage: AsciiMandelbrot iterations rows cols - where iterations  is  number  of
iterations  (default  100000),  rows  is number of printed rows (default 100),
cols is number of printed cols (default 100) AsciiMandelbrot -? for help

New in this 2.4 version (14-May-2020) * Optimized even further Altivec routines

New in this 2.3 version (10-May-2020) * After many researches  and  tests  now
Altivec routines are speeded up to 3x, processing 4 pixels per instruction!

New in this 2.2 version (04-Apr-2020) * Added GMP Library support only for OS4
MorphOS version is not changed because there isn't a porting of GMP Library

New in this 2.1 version (3-Nov-2019) * Default iterations  lowered  to  100000
for fast results on slowest machines

New in this 2.0 version (26-Oct-2019) * Now it's compatible  with  MorphOS!  *
Added some input controls * Some bugfixes and a lot of code added/rewritten

New in this 1.5 version (20-Dic-2018) * now  rendering  engine  and  resulting
computation time is separated from printing text routine on console window

New in 1.4 version (03-Nov-2018): * One executable for both  Altivec  and  non
Altivec  routines,  so no more crashes if you run the wrong exe! * Now you can
choose the number of iterations. * Elaboration time is printed on  screen  for
speedtest  purpose for bot Altivec and non Altivec calculations. * Added a new
charset to draw the Mandelbrot set.

"Bottomless wonders spring from simple rules, which are repeated without end."
cit. Benoit Mandelbrot

Enjoy, Amiga Rulez!
