High-rate streaming in WSN is required for future applications to provide high-quality information of battlefield hot spots. Although recent advances have enabled large-scale WSN to be deployed supported by high-bandwidth backbone network for high-rate streaming, the WSN remains the bottleneck due to the low-rate radios used and the effects of wireless(More)
Future applications for embedded systems demand chip multiprocessor designs to meet real-time deadlines. The large number of applications in these systems generates an exponential number of use-cases. The key design automation challenges are designing systems for these use-cases and fast exploration of software and hardware implementation alternatives with(More)
Modern day applications require use of multi-processor systems for reasons of performance, scalability and power efficiency. As more and more applications are integrated in a single system, mapping and analyzing them on a multi-processor platform becomes a multi-dimensional problem. Each possible set of applications that can be concurrently active leads to(More)
A virtual interface between Java and FPGA for networked reconfiguration is presented. Through the Java/FPGA interface, Java applications can exploit hardware accelerators with FPGAs for both functional flexibility and performance acceleration. At the same time, the interface is platform independent. It enables the networked application developers to design(More)
Many digital ICs can benefit from sub/near threshold operations that provide ultra-low-energy/operation for long battery lifetime. In addition, sub/near threshold operation largely mitigates the transient current hence lowering the ground bounce noise. This also helps to improve the performance of sensitive analog circuits on the chip, such as delay-lock(More)
—We present a design technique for (near) subthreshold operation that achieves ultra low energy dissipation at through-puts of up to 100 MB/s suitable for digital consumer electronic applications. Our approach employs i) architecture-level parallelism to compensate throughput degradation, ii) a configurable T bal-ancer to mitigate the T mismatch of nMOS and(More)
Ideally, bit-width analysis methods should be able to find the most appropriate bit-widths to achieve the optimum bit-width-to-error tradeoff for variables and constants in high level DSP algorithms when they are implemented into hardware. The tradeoff enables the fixed-point hardware implementation to be area efficient but still within the allowed error(More)
