MegaSampling: ultra-fast data acquisition

Duration: 18:13

This Tech Tues­day episode intro­duces MegaSam­pling, a high-per­for­mance data acqui­si­tion fea­ture of the TASKING debug­ger for ultra-fast, deter­min­is­tic sam­pling from embed­ded tar­gets.

Armin Stinger, Appli­ca­tion Engi­neer at TASKING, explains how MegaSam­pling works, what it can be used for, and where its lim­i­ta­tions are. The ses­sion cov­ers data pro­fil­ing, CPU load analy­sis, and XCP-based mea­sure­ment work­flows using TASKING winIDEA and iC7 Blue­Box debug­ger hard­ware.

What you will learn:

  • What MegaSam­pling is and how it works
  • How the iC7 Pro and iC7 Max enable high-speed data acqui­si­tion
  • How to sam­ple vari­ables from on-chip mem­o­ry with­out stop­ping the CPU
  • How MegaSam­pling can sup­port data pro­fil­ing and soft­ware behav­ior analy­sis
  • How pro­gram counter sam­pling can be used for CPU load dis­tri­b­u­tion analy­sis
  • How XCP clients such as Vec­tor CANoe can use MegaSam­pling for fast mea­sure­ment work­flows
