OpenCV in SystemC

Question

I have been using both OpenCV and SystemC for several applications with great satisfaction.

Now, I have this application where I need to display images with OpenCV in a SystemC simulation environment. For some reason however, both packages seem to be incompatible "at runtime":

• There is no problem when I call cvNamedWindow or cvShowImage in a SystemC class before sc_start() was called.
• However, when cvNamedWindow or cvShowImage is called in a sc_thread, the execution of the program is aborted:

  Thread 1: EXC_BAD_ACCESS(code=2, address=0x7c91ad70).

There is no problem with querying frames (cvQueryFrame), only window-related functions seem to cause problems. If someone has an idea what could cause this problem and if there is a solution or a work-around for this issue, that would be great.

P.S. I'm using Xcode, but I suppose that the problem is not related to the coding environment.

Answer 1

It won't work, SystemC doesn't support GUIs (Graphical User Interfaces).

Somebody did some research on this subject: Implementing a Graphical User Interface for SystemC

SystemC is an open source library used for developing models of software algorithms, hardware architecture and system-level designs. Although SystemC is very rich in possibilities for Hardware Description, the simulation is made via a console application, thus textual only, hence it is cumbersome to view the results. Our objective is to develop a GUI for SystemC to provide a more intuitive representation of simulation results. We will document our experiment and compare the cost, in terms of simulation time, of our solution.
