The C64x+ DSPLIB was developed by optimizing some of the functions of the
C64x DSPLIB to take advantage of the C64x+ architecture.
Table 3−10 shows the optimized functions for the C64x+ DSPLIB.
There are two optimization types:
-
SPLOOP conversion: Optimized code uses SPLOOP to provide
interruptibility and decrease power consumption. The new C64x+
instructions do not increase algorithm performance, and thus, are not
used.
-
Kernel redesign, SPLOOP: Kernel of algorithm rewritten to take
advantage of the new C64x+ instructions and of the SPLOOP feature.
