Texas Instruments TMS320C64X manual Cycles Nx / 4 + Codesize Bytes

DSP_dotprod

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.
