Graphical DSP programming - FIBULA
FIBULA
is a graphical user interface and integrated programming environnement for
digital signal processing. It comes with a large library of blocks
for telecom, control and audio (including complex, matrix and boolean types).
FIBULA generates super optimized assembly code directly (not C code)
for maximum efficiency!
FIBULA
handles multi-core processing!
Create
your own blocks (hierachical programming), either
from existing blocks or using the FIBULA high level macro
language to define a new graphical block.
Place probes on the program schematic and display the signals evolution inside the DSP in real
time!
Take control of the DSP program blocks parameters in real
time!
Check algorithms
execution time!

FIBULA allows to control DSP program blocks parameters from the PC in real
time, ideal for field experimentation:

FIBULA
generates optimzed assembly code, which allows a much more efficient use of the
ressources:

Example on computing Factorial 7:

FIBULA
T=130 cycles |
C
int fact(int x)
{if (x=1) {return 1}
else {return x*fact(x-1)} }
T=7336cycles
