dsPIC30F DSP Library
The dsPIC30F DSP Library provides a set of
speed-optimized functions for the most common digital
signal processing applications. The DSP Library
provides significant performance savings over
equivalent functions coded in ‘C’ and allows
developers to dramatically shorten their development
time.
The DSP Library is written predominantly in Assembly
language and makes extensive use of the dsPIC30F
DSC instruction set and hardware resources, including
X and Y memory addressing, modulo addressing,
bit-reversed addressing, 9.31 saturation and REPEAT
and DO loops. It provides functions for vector, matrix,
filtering, transform and window operations.
Features
• 49 total functions
