— In this contribution the modeling of power consumption for the VLIW processor TMS320C6416T is presented taking into account typical software algorithms in signal and image processing. The modeling is performed at the functional level making this approach distinctly different from other mod-eling approaches in low level technique. This means that the power(More)
The increasing demand for portable computing has elevated power consumption to be one of the most critical embedded systems design parameters. In this paper, we present a precise high-level power estimation methodology for the software loaded on a VLIW processor that is based on a functional level power model. The targeted processor of our approach is the(More)
— Compilers traditionally are not exposed to the energy details of the processor. In this paper, we present a quantitative study wherein we examine the influence of the global performance optimizations-o0 to-o3, of the code composer studio C/C++ compiler, on the energy and power consumption. The results show that the most aggressive performance optimization(More)
The increasing demand for portable computing has elevated power consumption to be one of the most critical embedded systems design parameters. In this paper, we present a qualitative study wherein we examine the impact of code transformations on the energy and power consumption. Three main categories of code transformations are investigated, namely data,(More)
Nowadays, most of communication systems are well suited for the evolving technology of Software-Defined Radios (SDR). Despite the wide variety of SDR applications, one trait is common among them which is the frequency hopping. Systems utilizing frequency hopping with high hopping rates have strong limitations on the frequency tuning time. In this paper, we(More)
Most Bluetooth implementations focus on architecture, routing protocols, encryption, and performance evaluation of the network. This paper provides a brief description of the Bluetooth standard including the physical layer. It focuses on developing MatLab/Simulink models for the Bluetooth transceivers utilizing different modulation schemes and the(More)
Energy efficiency has become a main challenge in Wireless Sensor Networks (WSNs) and their applications. Localization is one of the indispensable stages in WSN. Localization generally refers to the process of locating the position of one or more node(s) in a network. This paper develops and evaluates an improved energy aware localization algorithm in WSNs.(More)
