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
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. It provides functions for vector, matrix,
filtering, transform and window operations
