1. Code Size

  • Important criterion for processors with low on-chip memory

  • Object code size and actual code size are both important

  • The less complex algorithms ( radix algorithms ) have a smaller object code size

  • 2. performance

  • Excessive additions in FHT could be avoided depending on application

  • FHT is a better choice in memory critical applications

  • Compiler effects need to be accessed before direct comparison of algorithms
