The Paper is based on “Design and implementation of TMS320F28035 Digital Signal Processor (DSP) based digital controller for 2 kW switch mode power supply (SMPS)”.In the earlier research has implemented the analog controller, In the analog implementation of power controller comes with inherent disadvantage of aging, lack of flexibility, complexity in design etc. those are successfully overcomes...

Smart cameras are among the emerging new fields of electronics. The points of interest are in the application areas, software and IC development. In order to reduce cost, it is worthwhile to invest in a single architecture that can be scaled for the various application areas in performance (and resulting power consumption). In this paper, we show that the combination of an SIMD (singleinstructi...

We have proposed in this paper an embedded palmprint recognition system using the dual-core OMAP 3530 platform. An improved algorithm based on palm code was proposed first. In this method, a Gabor wavelet is first convolved with the palmprint image to produce a response image, where local binary patterns are then applied to code the relation among the magnitude of wavelet response at the centra...

Abstract This paper describes a mixed-signal integrated circuit implemented in low-cost CMOS technology optimized for dc/dc and ac/dc converter applications. The device is partitioned into a hardware digital controller comprised of a digital signal processor (DSP) controller and an instructionbased microcontroller (MCU) system management processor section. The hardware digital controller includ...

applications are mobile communication terminals, digital consumer equipment, and multimedia systems. One example of digital consumer equipment is the digital still camera. Hitachi has developed a digital camera system based on the SH-DSP (Fig. 1). ABSTRACT: Recently sales have grown markedly in the field of mobile communication terminals such as global system for mobile communications (GSM), pe...

SAD (Sum of Absolute Difference) algorithm is heavily used in motion estimation which is computationally highly demanding process in motion picture encoding. To enhance the performance of motion picture encoding on a VLIW processor, an efficient implementation of SAD algorithm on the VLIW processor is essential. SAD algorithm is programmed as a nested loop with a conditional branch. In VLIW pro...

The ongoing advances in semiconductor technology are the enabler for complete System on Chip (SoC) solutions. In this SoC domain Digital Signal Processors (DSPs) are employed to carry out software driven digital signal processing tasks. Although DSPs could still be modified in the SoC domain, they are mainly employed as fixed DSP cores. Possible adaptations to the embedding system cannot be car...

H.264/AVC is a new video compression standard designed for future broadband network. Compared with former video coding standards such as MPEG-2 and MPEG-4 part 2, it saves up to 40% in bit rate and provides important characteristics such as error resilience, stream switching etc. However, the improvement in performance also introduces increase in computational complexity, which requires more po...
