Embedded Systems with Reconfigurability: A Fresh Approach to Hardware/Software Separation

Abstract

The separation of hardware and software is a vital aspect in developing a flexible embedded system. In order to reach the high performance of dedicated hardware, computer architectures that can change their hardware to each application are being designed, and reconfigurable computing is a potential way to resolving the conventional trade-off between flexibility and performance. In this research, we first review and describe existing hardware and software partitioning techniques before proposing a novel approach for task division and scheduling that takes use of the dynamic reconfiguration and delay of reconfigurable hardware. The suggested method divides a massive programme into smaller, more manageable jobs, each of which is related to the others through constraints. And based on the sequence in which the activities were carried out, a directed acyclic graph (DAG) was created to illustrate the connections between them. Then, a method called GATS, which combines the Genetic Algorithm and the Tabu Search algorithm, is used to map the particular application described in the DAG to the hardware and software platform. Priority-based scheduling allows for the quickest possible assignment and execution sequence of tasks. The testing results demonstrate the method's strong performance and its ability to transfer the application task to the reconfigurable system.
