In order to optimize the power consumption of the mobile healthcare system, we analyze entire workload of the wearable healthcare signal processing and found that computation of digital filter is one of critical function in the workload. In this paper, we present the AHB based hardware digital filter in order to accelerate the computation of digital filter in signal processing which is processed on...
Most power reduction mechanisms for NoC channel buffers rely on on-demand wakeup to transition from a low-power state to the active state. Two drawbacks of on-demand wakeup limit its effectiveness: 1) performance impact caused by wakeup delays, and 2) energy and area cost of sleep circuitry itself. What makes the problem harder to solve is that solutions to either problem tend to exacerbate the other...
Mobile Augmented Reality (MAR) is an emerging visual computing application for the mobile Internet device (MID). In one MAR usage model, the user points the handheld device to an object (like a wine bottle or a building) and the MID automatically recognizes and displays information regarding the object. Achieving this in software on the handheld requires significant compute processing for object recognition...
