The main objective of this study is to introduce a simple, low-complexity and effective algorithm to evaluate the quality of the real-time electro-cardiosignal, especially the electro-cardiosignal coming from dry electrode, or the signal collecting during periods of muscular activity or excessive motion. In the proposed method, the real-time signal is pre-processed by five main steps:(1) down sampling...
The human body consists of many complicated physiological signals such as blood pressure, electrocardiograph (ECG), respiratory rate, electroencephalograph (EEG), arterial oxygen saturation (SpO2), body temperature and so on, which, to some extent, reflects the health conditions of the people. Long term and continuous monitoring of these signals are of much importance for the detection and treatment...
The ability to naturally interact with devices is becoming increasingly important. Speech recognition is one well-known solution to provide easy, hands-free user-device interaction. However, speech recognition has significant computation and memory bandwidth requirements, making it challenging to offer at high performance, real-time and ultra-low power for handheld devices. In this paper, we present...
In current Chip-multiprocessors (CMPs), a significant portion of the die is consumed by the last-level cache. Until recently, the balance of cache and core space has been primarily guided by the needs of single applications. However, as multiple applications or virtual machines (VMs) are consolidated on such a platform, researchers have observed that not all VMs or applications require significant...
As smart mobile devices become pervasive, vendors are offering rich features supported by cloud-based servers to enhance the user experience. Such servers implement large-scale computing environments, where target data is compared to a massive preloaded database. CogniServe is a highly efficient recognition server for large-scale recognition that employs a heterogeneous architecture to provide low-power,...
In an SoC, building local storage in each accelerator is area inefficient due to the low average utilization. In this paper, we present design and implementation of Buffer-integrated-Caching (BiC), which allows many buffers to be instantiated simultaneously in caches. BiC enables cores to view portions of the SRAM as cache while accelerators access other portions of the SRAM as private buffers. We...
Power consumption of the display subsytem has been a relatively less explored area compared to other components of a mobile device including computing, storage, and networking units, although the former often constitutes one of the most power-hungry portions of the system. Typical applications on a mobile device such as Web browsing and text editing tend to have rather static image content; each frame...
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...
