Trends in Design and Implementation of Signal Processing Systems [In the Spotlight]

The design and implementation of SP systems (DISPS) includes the development of software tools and methodologies to support the design of these complex systems. In its early days, DISPS focused on the hardware-based design of SP algorithms to meet real-time requirements. This topic was often called very large-scale integration (VLSI) SP. The emphasis has gradually shifted to include software and hardware/software codesign and implementation aspects. Programmable digital signal processors (DSPs) and embedded central processing units (CPUs) are now popular for real-time SP, such as mobile phones. Field programmable gate array (FPGA)-based designs are also replacing application-specific integrated circuits (ASICs) in many applications.
