Trends in Design and Implementation of Signal Processing Systems
Mohammad M. Mansour, Liang‐Gee Chen, Wonyong Sung · 2011
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. DISPS is now rapidly expanding to include multicore and many-core platforms for throughput demanding applications, low-power SP circuits for power-sensitive applications, and distributed implementations of emerging bioinspired and cognitive radio networks. This column gives an overview of these trends in DISPS as presented during the expert summary, which was organized by the DISPS Technical Committee at ICASSP 2011.
