High-Level Synthesis for Embedded Systems
Michael F. Dossis · InTech eBooks · 2012
Embedded systems comprise small-size computing platforms that are self-sufficient. This means that they contain all the software and hardware components which are “embedded” inside the system so that complete applications can be realised and executed without the aid of other means or external resources. Usually, embedded systems are found in portable computing platforms such as PDAs, mobile and smart phones as well as GPS receivers. Nevertheless, larger systems such as microwave ovens and vehicle electronics, contain embedded systems. An embedded platform can be thought of as a configuration that contains one or more general microprocessor or microprocessor core, along with a number of customized, special function co-processors or accelerators on the same electronic board or integrated inside the same System-on-Chip (Soc). Often in our days, such embedded systems are implemented using advanced Field-Programmable Gate Arrays (FPGAs) or other types of Programmable Logic Devices (PLDs). FPGAs have improved a great deal in terms of integrated area, circuit performance and low power features. FPGA implementations can be easily and rapidly prototyped, and the system can be easily reconfigured when design updates or bug fixes are present and needed.
