I was recently asked, \"Do you have some kind of list or simple rules to get high performance generated code using Real-Time Workshop?\" I put the question to my colleague (and first guest blogger<\/a>) Tom Erkkinen<\/a>, and he came up with the following.<\/p>\r\n

\r\n

    \r\n\t
  1. Use ERT based targets<\/a><\/li>\r\n\t
  2. Use Code Generation Advisor<\/a>, with efficiency as top priority<\/li>\r\n\t
  3. Inline parameters<\/a><\/li>\r\n\t
  4. For floating point, use single precision signals (if your application allows for it)<\/li>\r\n\t
  5. For fixed point, remove unnecessary saturation checks<\/a><\/li>\r\n\t
  6. Limit use of nonvirtual buses, except at model boundaries<\/a><\/li>\r\n\t
  7. Use reusable subsystems<\/a><\/li>\r\n\t
  8. Use TFL<\/a> when ANSI-C is insufficient<\/li>\r\n\t
  9. Use state machines only when really needed, otherwise consider using truth tables<\/a><\/li>\r\n\t
  10. Consider using Simulink lookup tables<\/a>, your legacy tables may not be as optimized<\/li>\r\n<\/ol>\r\nIf you would like to learn more, follow the links to appropriate resources.\r\n<\/p>\r\n\r\n
