There are whole brunches of program modules which automate the process of analysis and alternation of date in memories and processors ( CarRadios HPX , SE Dashboards HPX , MTRK Dashboards HPX , TMS HPX, Other HPX ) .These modules are not free. Their price is not fixed because their quantity is increasing continuously. All not free modules have file type *.hpx and are so coded that the user can't see their source code. In the other hand the free ones , with file type *.hpl , allow the user to examine their source code. Also the user can create by himself program modules. For this purpose a high level program language called HPL is used.
