DSP_autocor
4-5 C64x+ DSPLIB Reference
Implementation Notes
- Bank Conflicts: No bank conflicts occur.
- Interruptibility: The code is interrupt-tolerant but not interruptible.
- The inner loop is unrolled 8 times.
- The outer loop is unrolled 4 times.
- The outer loop is conditionally executed in parallel with the inner loop. This
allows for a zero overhead outer loop.
