We review the evolution of DSP architectures and compiler technology, and describe how compiler techniques are being used to optimize emerging DSP architectures. Such new architectures are characterized by the exploitation of data and instruction level parallelism while being an amenable target for a compiler, thereby reducing or eliminating the need to rely on assembly language programming and...

This paper presents an approach to implementing a fast FLC on a DSP in order to achieve high speed operation with a small sampling interval. This approach uses some specific techniques for hardware-software co-design, where hardware-specific properties of DSP architecture are utilized to reduce the number of computations required in software. The DSP approach is cost-effective and useful for pr...

This paper describes an H.263 video codec implementation based on a low power consumption general purpose DSP. Fast algorithms, such as a fast motion estimation algorithm and a low complexity noise reduction filter, are proposed to implement the video codec on a single DSP chip maintaining sufficient picture quality. By using a 50MIPS, 100mW DSP, the developed codec encodes and decodes 7.5 QCIF...

This paper describes a laboratory course at our institute using TMS320C3x and TMS320C4x digital signal processors (DSPs). This laboratory course is intended for graduate students in Electrical Engineering or Telematics. It aims at introducing DSP processors and their special features as well as at demonstrating the advantages of these features, based on different experiments. These experiments ...

This article is the first in a three part series describing techniques and methods for using MATLAB as an executable specification for hardware development. MATLAB, the defacto industry standard for DSP algorithm development, includes abstractions such as complex numbers, matrix operations, built-in and toolbox libraries of DSP functions and waveform analysis that make this language highly usef...

Recent strides in programmable logic density, speed and hardware description languages (HDL’s) have empowered the engineer with the ability to implement digital signal processing (DSP) functionality within programmable logic devices (PLD’s or FPGA’s). This paper, written for the intermediate DSP engineer or logic designer, begins with an overview of general DSP concepts. Filter design principle...

BACKGROUND Distal sensory polyneuropathy (DSP) is a common complication of HIV disease. Its effects on quality of life (QOL) and function have not been well described. OBJECTIVE The study objectives were: (1) to compare QOL and lower extremity function in people with HIV-related DSP and people with HIV disease who do not have DSP, (2) to determine the extent to which function predicts QOL, (3...

OBJECTIVE The prevailing hypothesis that early subclinical small-fiber injury precedes large-fiber damage in diabetic sensorimotor polyneuropathy (DSP) is based on lower intraepithelial nerve fiber density in type 2 prediabetic patients despite normal nerve conduction studies (NCSs). We aimed to confirm the same hypothesis in type 1 diabetic patients by examining whether: (1) subjects without D...

Root resorption is an unwanted effect of orthodontic tooth movement. Analysis of dentine proteins in gingival crevicular fluid (GCF) is a potentially safer method of quantifying root resorption compared with conventional radiographic methods. This study aimed to identify and quantify the dentine-specific matrix protein, dentine sialoprotein (DSP), released into GCF during physiological root res...
