Where to Optimize?

• The 80/20 rule
  • 20% of the software uses 80% of the processing time
  • and 80% of the software uses 20% of the processing time

• DSP algorithm software spends most of its time in loops
  • This is where optimization for speed and power is most valuable

• Control software takes up the bulk of the program memory, but only a fraction of the processing time
  • Control software is the best candidate for memory optimization
