How to make compilers more useful for developing DSP applications and reduce reliance on assembly coding has long been a topic of interest in the DSP community. This paper presents Siemens solutions for supporting its TriCore DSP/microcontroller architecture, including SIMD instructions, at the C/C++ level. Two solutions based on either extending C/C++ language with the new built-in DSP data ty...

This paper proposes the possibility of reuse of the existing optimized DSP code on a scalable high-performance VLIW DSP processor. Since loops are the critical paths in most DSP applications, we focus on issues related to loop optimization. In our approach, we first perform a loop alignment transformation on the source level; we then reuse the existing optimized loop code on the assembly level....

Electronic products are currently seeing a phenomenal increase in the amount of Digital Signal Processing (DSP) tasks being performed. In many cases, software realizations of these algorithms running on DSP chips are too slow and consume too much power, therefore mandating hardware implementations. In addition to the use of ASICs for high performance DSP algorithms, Field-Programmable Gate Arra...

The rapid increase in digital signal processing (DSP) applications has generated a strong demand for electrical engineers with DSP backgrounds; however, the gap between industry needs and university curricula still exists. To answer this challenge, a sequence of innovative DSP courses that emphasize hands-on experiments and practical applications were developed for continuing education in elect...

This paper presents a new methodology for software compilation for embedded DSP systems. Although it is well known that conventional compilation techniques do not produce high quality DSP code, few researchers have addressed this area. Performance, estimated power dissipation, and code size are important design constraints in embedded DSP design. New techniques for code generation targeting DSP...

Data acquisition for real-time applications on a DSP board is an engineering challenge. Currently DSP engineers can take up to one and a half years to develop a Visual C++ program. End users with limited programming skills cannot take advantage of the strength of DSP functionality, while DSP programmers cannot satisfy the time-to-market requirements of their customers. Data Translation has reso...

BACKGROUND Protease inhibitors (PI)s have been associated with distal sensory polyneuropathy (DSP) and metabolic complications in high-income countries. No data exist in Africans where second-line antiretroviral therapy (ART) often include PIs. METHOD We performed a cross-sectional study to assess the DSP frequency and metabolic risk factors in community-based South Africans taking ritonavir-...

Classic embryological studies have documented the inductive role of root dentin on adjacent periodontal ligament differentiation.  The biochemical composition of root dentin includes collagens and cleavage products of dentin sialophosphoprotein (DSPP), such as dentin sialoprotein (DSP).  The high abundance of DSP in root dentin prompted us to ask the question whether DSP or peptides derived the...

Neurotropin is a nonprotein extract isolated from inflamed skin of rabbits inoculated with vaccinia virus, and used for treatment of neuropathic pain. In the present study, we have determined whether neurotropin could exert antinociceptive action using the central neuropathic pain model that we recently established. Rats were randomly allocated to 3 groups: Sham group (n=20), DSP-4 [N-(-2-chlor...
