This paper presents a programmable DSP platform for Digital Still Cameras based on the Texas Instruments TMS320C54x family. One major advantage of this platform is that, after capturing an image from a CCD sensor, processing the raw image, and compressing the image for storage is performed on the Digital Signal Processor (DSP). This provides a short shotto-shot delay and a high degree of flexib...

This paper proposes a hybrid single carrier sinusoidal modulation suitable for multiphase multilevel inverters. Multiphase multilevel inverters are controlled by hybrid modulation to provide multiphase variable voltage and a variable frequency supply. The proposed modulation combines the benefits of fundamental frequency modulation and single carrier sinusoidal modulation (SC-SPWM) strategies. ...

Wireless systems based on CDMA such as proposed in the 3GPP standard utilize pseudo random number sequences for generation of the spreading codes. These sequences are usually created by the use of finite field arithmetic. A pure software implementation onto a digital signal processor (DSP) is very inefficient and would result in unreasonable high computational load. In this paper a hardwarebase...

In this paper the implementation of a contour tracking procedure is presented. If a rough contour of the desired structure is available on the first frame of a sequence, the contours on the subsequent frames are automatically outlined in real time. Furthermore, indices of clinical interest are calculated from the computed contour and they are graphically displayed in real time. The software run...

Parallelization is one possibility to enhance the performance in processors. For singleinstruction-multiple-data (SIMD) processors one requirement is the possibility to parallelize algorithms so that one algorithm is partitioned to the parallel processing units of the processor. This means that data has to be exchanged between the processing units. Hence, these separate units have to be connect...

In the industrial application, induction motors (IMs) and digital signal processing (ZQ28335) combination are very important in scientific field. Two thirds of consumption electricity is due to motor driven equipment. The direct torque control (DTC) standard industry it has fast response system applications. drawback DTC flux ripples measurements. scalar can be considered as a solution this but...

A software defined radio (SDR) prototype based on a multiprocessor architecture (MPA) is developed. Software for Japanese personal handy phone system (PHS) of a 2G mobile system, and IEEE802.11 wireless LAN, which has much wider bandwidth than the 2G systems, is successfully implemented. Newly developed flexible-rate pre-/post-processor (FR-PPP) achieves the flexibility and wideband performance...

Rapid evolution of wireless standards and the increasing demand for multi-standard products make traditional fixed-function hardware for baseband processing too rigid. Programmable solutions are needed. At the same time, traditional DSP architectures cannot meet cost and power requirements in handheld devices. As a response to this, a new processor architecture dedicated for baseband processing...

This paper presents an application-specific digital signal processor for third generation wireless communications. The processor architecture and instruction set are specially designed for the WCDMA system.
