iSYSTEMTechBlog: Multiple Special Function Register Definitions supported

Since winIDEA 2011 build 53 (9.11.53) multiple special function registers (SFRs) can be defined for a CPU. In the CPU specification, names of multiple CPUs or modules can be combined with the + sign. This allows adding a few SFRs for a CPU.

In the beside example the default registers for MPC5567 are used with addition of SFRs specified in external definition MySFRs.

Additional custom SFRs files (*.SFR, *.SFG) can be placed in the newly imple-mented SFR subfolder of winIDEA.

After the next restart of winIDEA the custom SFRs will be available.

iSYSTEMTechBlog: Analyzer supports now Line Execution Profiling

Since winIDEA 2011 build 49 (9.11.49) the analyzer supports now line execution profiling.

This feature is available in Entry/Exit and also in Range mode.

Line execution profiling can help to detect performance bottlenecks in a function's code.

To setup this feature select in the "Profiler Configuration" dialog the function name you like to profile and check the box "Include function lines" below the function list.

With that setting the profiler shows timeline measurements for every line of that function in the views "Timeline" and also in "Statistics".

The statistics criteria available are:

• Count
• Net Time
  time spent in the function only (without interrupts, without subroutines)
• Gross Time
  time spent between function entry and exit, including subroutine calls, but without interrupts
• Call Time
  time spent between function entry and exit including interrupts and subroutine calls

 

 

iSYSTEMTechBlog: winIDEA Debug Plug-in verified with Eclipse 3.7.0 (Indigo)

Since winIDEA 2011 build 50 (9.11.50) the debug plug-in has been verified for Eclipse 3.7.0 (Indigo). The existing debug plug-in works fine without changes.

winIDEA is fully integrated into the Eclipse debug environment. Using an iSYSTEM debug plug-in for Eclipse you can use the full debugging capabilities of winIDEA and iSYSTEM´s debuggers from within Eclipse. Eclipse is used as an editor, a project & build manager as well as a debugger. It provides all standard CDT debugger functionality, plus SFR (Special Functions Register) view and Real-time Expressions view. iSYSTEM also provides a Regular Expression Error Parser Plug-in for CDT.

The iSYSTEM debug plug-in provides more than CDT debugger, but less than winIDEA. Comparing to winIDEA, the plug-in does not implement trace, execution coverage and profiler functionality. winIDEA still runs in the background, but during debugging no switching to winIDEA is necessary.

Beside Ganymede (Eclipse 3.4), Galileo (Eclipse 3.5), Helios (Eclipse 3.6) iSYSTEM now also supports Indigo (Eclipse 3.7.0) . All necessary documentation and downloads can be found here:

iSYSTEMTechBlog: Profiler supports now negative Wildcards

Since winIDEA 9.11. build 47 iSYSTEM's new analyzer supports now negative wildcards in profiler's Statistics and Timeline view. Negative wildcards are supported using the - prefix.

Press the filter button in the profiler menu to show the profiler filter dialog and specify a negative filter, e.g. " -OS* -Adc".

This will tell the profiler not to show functions that names start with "OS" and "Adc".
