— 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)
— 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)
— 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)

— Since performance and power consumption optimizations are crucial issues in embedded systems, it is necessary to find a trade-off between these optimization goals. This paper explores the performance and power trade-offs of VLIW processor , specifically the Texas Instruments TMS320C6416T DSP. We evaluate the effect of the global performance optimizations(More)
This paper introduces a VHDL realization of a new efficient intra prediction scheme that aims to enhance the compression efficiency of the H.264 standard. The new proposed algorithm is called Best Prediction Matrix Mode (BPMM). The main idea behind the new prediction scheme is to combine the most usable intra prediction modes, {vertical-horizontal-DC}, into(More)
