Mapusoft's OS simulator facilitates application development by emulating host hardware/software, allowing modular testing and resource optimization. It supports various operating systems including Linux/Posix and Windows, enabling complex embedded application testing on a host PC. Benefits include reduced testing effort, modular testing capabilities, and efficient simulation of hardware interfaces.

1. Overview Datasheet
In general, OS simulators provide support for developing applications by mimicking the host computer
hardware/software and often behave as a virtualization platform for the developer. Not all the
developers/testers can have access to the actual OS licenses and/or hardware. MapuSoft’s OS
Simulator is designed to create a better simulation environment.
OS Simulator consists of AppCOE, a powerful Eclipse-based IDE as its underlying platform and
includes all the interfaces provided by MapuSoft: OS Abstractor, Linux/POSIX, µITRON, pSOS,
Windows, VxWorks and Nucleus. MapuSoft’s OS simulator can also be used as a virtualized test bench
for complex embedded applications.

2. WHY USE OS SIMULATOR?
• Reduce testing effort by using a host rather than the resource restricted target platform
• Simulate a complex system on one host machine and save money by eliminating the need for using
expensive target platforms
• Perform modular testing by connecting application modules loosely via a simulated communication
interface
USING OS SIMULATOR AS A VIRTUALIZED TESTING PLATFORM:
OS Simulators provide the ability to simulate, test and run an entire system of C/C++ applications developed
for Linux/POSIX, micro-ITRON, pSOS, Windows, VxWorks and Nucleus on a host PC for the target OS. It
allows applications to take full advantage of powerful resources like CPU, memory, drivers, middleware and
tools on the host platform so that testing of the application can start before those target components are ready.
Following are the OS Simulator benefits when used as a Virtualized Testing Platform.
• OS Simulator allows you to do modular testing
> Modules can be broken down into separate processes with dedicated heap memory
> Ability to develop the low level communication mechanism across modules using user shared tiered
memory pools
> Load modules dynamically from a module (or) statically via the command prompt
• Easy to simulate and test the low level hardware interface either on shared memory or via a device driver
thread/process
• Can load other modules dynamically from any module (or) also statically load via command prompt
• OS Simulator allows a standalone application (block) as a separate fully independent process and can
also be dedicated to run on a single core under SMP
• OS Simulator allows interdependent multiple applications (blocks) as individual processes, which can
interact and share resources that are not marked private
