Blind Signal Separation for Cognitive Radio
Many efforts have been dedicated to cognitive radio research and many schemes have been proposed for cognitive radio in the past few years. Unfortunately, an important piece of cognitive radio, namely, signal ...

Open AccessDataflow-Based Map** of Computer Vision Algorithms onto FPGAs
We develop a design methodology for map** computer vision algorithms onto an FPGA through the use of coarse-grain reconfigurable dataflow graphs as a representation to guide the designer. We first describe a...

Redundancy Removal during High-Level Synthesis Using Scheduling Don‘t-Cares
Previous work in automata theory has shown how to eliminate sequential redundancy from networks of FSMs by finding sequences of inputs and outputs which are never communicated between components of the network...

System Specification
We describe the embedded system behavior by task graphs. The task graph model is similar to those used in distributed system scheduling and allocation problems [36, 80, 76, 55]. The task graphs represent what fun...

Chapter
Sensitivity-Driven Co-Synthesis
This chapter describes new techniques for the co-synthesis of real-time distributed embedded systems. Embedded system synthesis is co-synthesis because the hardware and software must be designed together to me...
