DSP_iir
4-55 C64x+ DSPLIB Reference
Special Requirements
- nr is greater than or equal to 8.
- Input data array x[ ] contains nr + 4 input samples to produce nr output
samples.
Implementation Notes
- Bank Conflicts: No bank conflicts occur.
- Interruptibility: The code is interrupt-tolerant but not interruptible.
- Output array r1[ ] contains nr + 4 locations, r2[ ] contains nr locations for
storing nr output samples. The output samples are stored with an offset
of 4 into the r1[ ] array.
- The inner loop that iterated through the filter coefficients is completely
unrolled.
Benchmarks Cycles 4 * nr + 21
