Abstract
Recent years has seen a tremendous increase in processing requirements of present-day embedded system applications. Embedded systems consist of multiple processing elements (PEs) connected to each other using different types of interfaces. Many complicated tasks are accomplished by embedded systems in varied settings, which may introduce errors during inter-processor communication. Testing such systems is tremendously difficult and challenging from testing non-real time systems. A major part of testing real time embedded systems involves ensuring accuracy and timing in synchronous inter-process communication More specifically, the synchronization and inter-processor communication of real-time applications makes testing a challenging task and due to the demand for higher data rate increases, day-by-day, making testing of such systems even more complex. This paper presents a novel frame work that uses multiple instances of simulators with physical high-speed serial interfaces to emulate any real time embedded system communication. The framework presents a testing technique that detects all faults related to synchronization of high-speed synchronous serial interfaces in a systematic manner. The novelty of our approach is to simulate communication across multiple processors in a simulation environment for detecting and localizing bugs. We verify this framework using a case study consisting of an embedded software defined radio (SDR) system. The test results show the applicability of our approach in fixing bugs that relates to synchronization issues that otherwise are very hard to find and fix in very complicated systems, such as SDR.

The instances of simulators were developed to proposed simulate the synchroextracts and localizes the bugs automatically
Summary
Embedded systems are a combination of hardware and software that execute a particular task. Embedded systems usually have either a single task or a minimum number of associated tasks that they have been programmed to complete These types of devices interrelate with the physical environments that they operate in. A real-time embedded system uses the features of both a real-time system and an embedded system It is part of a larger device with a dedicated function managed by a real-time operating system (RTOS), and has real-time computation and resource constraints. Their processing power and memory capacity are low relative to desktop computers, and the response time is among the most important key requirements. Communication, and parallelism might be balanced [1]
