Live Q&A - The Power of a Look-up Table
A great talk on a subject not talked about enough - and thank you for your service, Nathan.
Good talk. I think you meant 0.5mm accuracy, not 0.5cm at 03:30 in? The library function performance depends on if you have a double or single precision MMU. One major advantage of tables is ensuring all cases/states are covered, easily missed in complex nested if else statements. I’ve used a variation of memoisation, where the tables are.stored in RAM and fully computed once during initialisation when there’s time to do so. I’ve found a good use for them in generic UART configuration and handlers. There are examples of table-based initialisation of tasks in Jacob’s book. I partcularly liked your button metadata and CLI parser.
Thank you very much Nathan, I am always looking forward to your talks in the conference. I really appreciate your thorough investigation and great delivery. Thanks for the book recommendation.
Thanks for that thorough presentation on lookup tables. I think you touched on every way I have used lookup tables over the years and more.. A classic use case is for really fast CRC generation. Thanks for providing the links. Good stuff.
Great talk, Nathan! I loved how you applied LUTs in different practical applications and also provided additional links for reading. Thank you so much. I sometimes forget how invaluable and expandable LUTs are.
Slides are now posted. Sorry about the delay, folks!
An excellent presentation on an often overlooked aspect of embedded systems design.
