In embedded system design, hardware/software (HW/SW) partitioning is the NP-complete problem which searches reasonable composition of hardware and software components which not only satisfies the constraint of hardware but also optimizes the execution time. Blocks derive from the functional specification internally represented as control/data flow graph. In this paper, the model of the embedded system...
An embedded system, a digital electronic system being embedded in a larger device, is the system to be configured to fulfill specific demands of customers from some market segmentations. This nature complicates the design of an embedded system itself. Traditional embedded system marketers usually defined the systems based on their intuition, which could be subjective and misleading. To fulfill different...
The Embedded Systems Portability project investigates how to acquaint students in an engineering science curriculum with several important modern trends and practices in embedded system design. An overview of the program is given, and the specific objectives of several elective courses in electrical engineering are presented. The project also aims to provide a flexible but powerful controller for...
Low-power embedded system design has become extremely important in the most recent years. To fulfill system-level design requirements and time-to-market constraints, a power-driven methodology is essential during embedded system design. The aim of this paper is to introduce accurate and efficient power metrics included in a hardware/software (HW/SW) co-design environment to show the system-level partitioning...
In this paper, we use Genetic Algorithm to do the embedded system hardware-software co-design. The result indicates that the Genetic Algorithm can solve the problem of embedded system hardware-software co-design. An important task of embedded system design is to find an effective way of hardware-software implement. Since Genetic Algorithm is a very effective way to solve combination optimization problem,...
The process of embedded system design on reconfigurable architectures needs smart solutions to reduce development life-cycle and to use resources efficiently at run-time. Current solutions are insufficient to enable the embedded system designer to reflect the flexibility that a reconfigurable architecture can offer. Some of the basic problems are lack of flexible operator definitions, very detailed...
Embedded system design is a topic of interest to multidisciplinary fields including electrical engineering and computer science. In order to correctly focus on the correct aspects of embedded system design, be it hardware for electrical engineering students, or software for computer science students, seamless connectivity between the hardware and software aspects needs to be provided. One approach...
Hardware/software partitioning is a crucial problem in embedded system design. In this paper, we provide an alternative approach to solve this problem using particle swarm optimization (PSO) algorithm. Performance analysis of the proposed scheme with integer linear programming, genetic algorithm and ant colony optimization technique has been compared using standard benchmark datasets, and the computer...
High-level cost and performance estimation, coupled with a fast hardware/software co-simulation framework, is a key enabler to a fast embedded system design cycle. Unfortunately, the problem of deriving such estimates without a detailed implementation available is difficult. In this paper we describe two approaches to solve software cost and performance estimation problem, and how they are used in...
