In this section, an efficient hardware/software (HW/SW) architecture for ELM is presented. The proposed architecture is suitable for FPGA based implementations of intelligent embedded systems [10]. An embedded system is a special purpose computing platform designed to perform one or several dedicated functions. They are often designed for a particular kind of activity that is required to work under certain constraints, such as low power consumption, real-time operation, or security. In addition, low cost, and small size/weight are also typical requirements for these computing platforms. In the progress towards a more autonomous and flexible lifestyle, with new levels of comfort and safety, many embedded platforms have emerged on the market and are in use in our daily activities
