4-61 C64x+ DSPLIB Reference
Implementation Notes
- Bank Conflicts: No bank conflicts occur if the input arrays x[ ] and y[ ] are
offset by 4 half-words (8 bytes).
- Interruptibility: The code is fully interruptible.
- The code is unrolled 4 times to enable full memory and multiplier
bandwidth to be utilized.
- Interrupts are masked by branch delay slots only.
- Prolog collapsing has been performed to reduce codesize.
