Summary
The dsPIC® DSC DSP Library provides a set of speed
optimized functions for the most common digital signal
processing applications. This library provides significant
performance savings over equivalent functions coded in
C and allows developers to dramatically shorten their
development time. The dsPIC DSC DSP Library is written
predominantly in Assembly language and makes extensive
use of the dsPIC DSC 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.
