Hi everyone,
I'm new to programming DSPs, however wiling to learn new. Currently I
work
with ADSP2189M in VisualDSP++ 3.0 Enviroment. I started with Assembler and
created simple interface for ADSP2189M. My aim is to implement a Kalman
filter. Although I have an optimized C code for Kalman filter
unfortunatelly rest of my project is in Assebmler. I have no idea how to
implement a C code procedures into Assembler prgram. Rewriting the whole program
in C would be very time consuming for me. Please is there any .pdf or tutorial
somewhere describing how to implement C functions into asssembler code? How it
can be done in VisualDSP++ 3.0? May be a trick with compiler, I do not know ...
It would help me very much.
Thanks to you all
C, ASM and Kalman filter

there should be an option to create assembler output from the compiler.
It is usually -s or -S on a command line. See if you can create a make
file and execute it by hand, or modify the options line in the VDSP
environment (somebody here should know how to do that).
There is also a way to interface assembler and C. The linker manual
should explain that.
So it should be possible to use what you already have without that much
effort. It's just setting things up so the software is happy!
Patience, persistence, truth,
