Description
The DSP Library is written
predominantly in assembly language and makes extensive use of
the dsPIC30F DSP instruction set and hardware resources,
including X and Y memory addressing, modulo addressing,
bit-reversed addressing, 9.31 saturation, and REPEAT and DO
loops.
The DSP Library provides functions for the following types
of operations:
• Vector Operations
• Matrix
Operations
• Filtering Operations
• Transform
Operations
• Window Operations |
Features
• FEATURED DOWNLOADS
• 49
total functions
• Full compliance with the Microchip
dsPIC30F C30 Compiler, Assembler and Linker
• Simple user
interface – just one library file and one header file
•
Functions are both “C” and assembly callable
• FIR
filtering functions include support for Lattice, Decimating,
Interpolating and LMS filters
• IIR filtering functions
include support for Canonic, Transposed Canonic and Lattice
filters
• FIR and IIR functions may be used with the filter
files generated by the dsPIC30F Filter Design program
•
Transform functions include support for in-place and
out-of-place DCT, FFT and IFFT transforms
• Window
functions include support for Bartlett, Blackman, Hamming,
Hanning and Kaiser windows
• Support for Program Space
Visibility
• Complete function profile information
including register usage, cycle count and function size
information
Devices Supported
All processors in the dsPIC30F
family
Getting Started
• Read the summary section of
this web page
• Read the “Using the DSP Library” section in
the MPLAB C30 Libraries manual.
• The DSP library file
“libdsp.a” should be located in your C30 language tools “lib”
folder.
• The DSP library header file “dsp.h” should be
located in your C30 language tools “include” folder. |
