What are some common challenges DSP programmers face when optimizing algorithms for real-time systems?

DSP Programmers often encounter challenges related to ensuring that signal processing algorithms run efficiently within strict time and resource constraints. Real-time systems require low-latency processing, so optimizing code for speed and memory usage is critical. This may involve working with limited hardware resources, fine-tuning algorithms for specific DSP architectures, and debugging timing issues. Collaboration with hardware engineers and system architects is also essential to align software performance with overall system requirements.
