Software-Only Hardware Simulation

Figure 1: There is a parallel between the embedded target and host environment. Equivalent entities are shown on the same level.

Simulating embedded hardware in a Windows environment can significantly reduce development time. In this article, Michael Melkonian provides techniques for the software-only simulation of embedded hardware. He presents a simple example of an RTOS-less embedded system that uses memory-mapped I/O … Continue reading
