Digital Signal Processing (DSP) is a significant and increasing subject area in many disciplines such as, Electrical/Computer Engineering (ECE), Communication Engineering, Computer Science and other Engineering/Science disciplines. With the growing of DSP job market, the DSP course has become very popular among ECE students, and it is still considered to be a difficult and complex one to study....

In this paper, the implementation of a digital signal processor (DSP) based multi-format decoder for an IP set-top box is described. Using several software optimization techniques, the multi-format decoder has been fitted into a TMS320DM641 DSP @ 480 Mhz. Starting from a native C code implementation, a six-step software optimization process has been applied to improve the decoder performance. C...

Digital signal processors (DSP) are widespread in real-time systems. In the last ten years phase-locked loops have widely been used in DSP as control devices correcting a clock skew. In this paper new type of floating phase locked loops for DSP is designed. For the floating phase locked loops new stability conditions are obtained.

Co-design of digital signal-processing (DSP) algorithms and power-amplifier characteristics can lead to improved efficiency and linearity through a variety of strategies including: predistortion, DSP control over bias conditions, particularly the power supply voltage, and DSP generation of digital input signals for switching amplifiers. This paper discusses several amplifier architectures that ...

We have developed a new-generation, general-purpose digital signal processor (DSP) core with low power dissipation for use in third-generation (3G) mobile terminals. The DSP core employs a 4-way VLIW (very long instruction word) approach, as well as a dual-multiply-accumulate (dual-MAC) architecture with good orthogonality. It is able to perform both video and speech codec for 3G wireless commu...

The performance of current C compilers for DSP is almost unacceptable. One of the most important reasons is the lack of implementing software pipelining. This paper presents a remedy called source-level loop optimization. DSP programmers can use source-level loop optimization first then input its result to the DSP compiler to obtain better assembly code. The implementation of source-level loop ...

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...

Military sensor-driven systems normally use FPGAs to interface with the analog to digital converters (ADCs) that digitize sensor inputs. The ADCs operate at rates of up to 3 MSPS, which requires very high-performance digital signal processing (DSP) circuitry, often implemented by FPGAs optimized for such DSP applications. The Altera® 40-nm FPGA families, capable of unprecedented density and per...

Field-Programmable Logic (FPL) is on the verge of revolutionizing digital signal processing (DSP) in the manner that programmable DSP microprocessors did nearly two decades ago. While FPL densities and performance have steadily improved to the point where some DSP solutions can be integrated into a single FPL chip, they still have limited the use in high-precision high-bandwidth applications. I...
