New communication standards and high channel aggregation system requirements are pushing Digital Signal Processing (DSP) system performance requirements beyond the capabilities of digital signal processors. Altera’s new Stratix field-programmable gate array (FPGA) family includes embedded DSP block multipliers and large numbers of shallow memories with huge I/O bandwidth, making them an excelle...

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...

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...

Digital Signal Processors (DSPs) are employed in all fields of multimedia applications such as speech, audio, modem, video, or graphics. Often, they are embedded into multimedia systems as a System on Chip (SoC) component. Although DSPs could still be modified in the SoC domain, they are mainly employed as fixed DSP cores. Possible adaptations to the embedding system are not carried out. Thus, ...

A DSP-based mixed signal tester with feedback capability provides great flexibility and versatility in real-time mixed signal device testing. In this project, a DSP-based feedback loop system is designed and implemented for the DSP module of Schlumberger's new mixed signal tester. This DSP-based feedback loop system provides a dynamic close-loop testing environment for waveform generation and d...

This paper presents the hardware design of a real time tracking system based on DSP/FPGA regarding the research and development of a certain type of short range defence radar. In this tracking system, the FPGA is used as a floating point co-processor of the fixed point DSP, and the large amount of calculation of the debiased converted measurement Kalman Filter (DCMKF) algorithm is realized in F...

This study explores how the metal materials of the applicator influence the dose distribution when performing brachytherapy for cervical cancer. A pinpoint ionization chamber, Monte Carlo code MCNPX, and treatment planning system are used to evaluate the dose distribution for a single Ir-192 source positioned in the tandem and ovoid. For dose distribution in water with the presence of the tande...
