Upload and run example
Return to the IP Explorer home page, and select Simulate Processors.
The My Cortex-M0 and My Cortex-M7 instances you created previously should be listed at the top.
Select My Cortex-M0 and navigate to Software Simulation section. Click +New to open the Start a new Software Simulation pane.
From the Select/Upload Software pulldown, select +New.
Browse for the custom-software.tgz tarball created previously, and upload.
When processed, select my_example from the pulldown.
Select AC6 (Arm Compiler for Embedded) as the compiler, and then click Run.
While the Cortex-M0 simulation is being processed, you can repeat for the My Cortex-M7 system.
You will receive email notification when each simulation run is complete.
Compare results
When execution is complete, you will see a summary of the performance of your application for each system.
The Cortex-M7 used in the simulation includes a Floating-Point Unit (FPU) which could execute the floating point addition directly. The Cortex-M0 used a C library routine.
