The need to process multimedia data places largecomputational demands on portable/embedded devices.These multimedia functions share commoncharacteristics: they are computationally intensive anddata-streaming, performing the same operation(s) onmany data elements.The Reconfigurable StreamingVector Processor (RSVPTM) is a vector coprocessorarchitecture that(More)
and utilization in field-programmable logic requires new FPGA architectures. Problems with existing architectures include low resource utilization, routing congestion, high interconnect delay, and insufficient I/O connections. At Northeastern University, we have developed a novel three-dimensional FPGA architecture called Rothko, aimed at solving some of(More)
Next generation mobile devices will continue to demand high processing power for imaging applications. The expected performance is in the class of supercomputers, but delivered with limited energy and memory bandwidth for embedded systems. This paper advocates a streaming computation model that leverages the deterministic access patterns in imaging(More)
Current trends in the sensor networking research community indicate a shift in focus from the traditional research targeting enterprise, structural/industrial monitoring applications to more consumer focused applications. In this paper we discuss an ongoing project in our lab in the “people-centric” mobile device-based sensor networking area. We present an(More)
An important mechanism to conserve energy and extend the battery life of low-power wireless networks is to increase the sleep-cycle of the nodes. However, increasing sleep-cycles can have unintended consequences on the application performance. Therefore, it is important to understand the impact of various sleep-cycle parameters on the performance of any(More)
Web TV is making a comeback, as users increasingly co-consume TV related web content on their companion devices (tablets and smartphones) in sync with TV watching. In this `dual screen' experience, users download and invoke TV apps on their companion devices to personalize their Superbowl or American Idol TV experience with a web counterpart. Unfortunately,(More)
