Software Defined Radio (SDR) allows dynamically changing protocols and functions in order to provide flexible, multiple-standard services to users. A reconfigurable baseband architecture having a set of coarse-grained, heterogeneous execution units is one strategy which can meet this requirement. However, while we can integrate a large number of execution units onto a chip, conventional bus structures...
New trends in wireless communication systems require multi-standard coexistence and high data rates. In order to meet these requirements, we propose a reconfigurable baseband platform with coarse grained heterogeneous execution units and flexible interconnections, which are controlled by configuration information. In addition, we demonstrate the effectiveness of our approach in three sample implementations,...
With the continued development of RFID technology, a large number of RFID tags are being deployed having different protocols. Hence, a multiprotocol interrogator which can support all of these alternatives has become a design requirement for many systems. While multifunction capability may be implemented using a high performance DSP, CPU or FPGA, those solutions have a large area cost, so an innovative...
An efficient and configurable computational platform is indispensable in order to meet multiple wireless communications standards. We have developed a heterogeneous reconfigurable architecture to support the arithmetic, logic and signal processing functions which are required for transceivers used in standardized wireless local area networks. Each execution unit in this reconfigurable architecture...
