The speed of current PCs enables them to decode and play an MPEG bitstream in real time. The encoding process, however, cannot be done in real-time. The purpose of this thesis is to produce a low-cost real-time Digital Signal Processor (DSP) implementation of an MPEG encoder. The DSP will provide an MPEG bitstream to the PC that can be saved to disk. The input to the DSP will be an analog audio...

Digital signal processing (DSP) technology is the core of many modern application areas. Computer vision, data compression, speech recognition and synthesis, digital audio and cameras, are a few of the many fields where DSP technology is essential. Although Moore’s law continues to hold in the semiconductor industry, the computational demands of modern DSP algorithms outstrip the available comp...

The recent rapid increase in applications of DSP has generated a need for technical personnel with a DSP background. Until recently, most DSP education has been at the graduate level, so many practicing engineers are developing a need for additional DSP education. At Georgia Tech we are delivering an online continuing education course that is targeted at these engineers. The 12-week course is c...

The DSPstone evaluation methodology is applied to evaluate performance of xed{ and oating{point digital signal (DSP), and general purpose (GPP) processors with appropriate C compilers. Main goal was to estimate run{ time e ciency on code which is representative for baseband processing in multimedia applications. The results show that for DSP{type code, like FIR ltering, DSP processors are super...

This paper describes digital signal processing (DSP) microprocessor experiments designed for university juniors majoring in electric & electronic (E & E) engineering. At the time of enrollment, most students have only studied the curriculum for analog signal processing which is taken in the prior semester. The proposed DSP microprocessor experiments are included along with analog signal process...

The digital signal processor (DSP) industry has been growing steadily over the past few years due to strong demands for digital signal processors in a variety of applications. Among these applications, wireless communication accounts for more than two-thirds of the DSP market today. The Selectable Mode Vocoder (SMV) is a third generation (3G) speech coding technology that provides significant c...

FPGAs have been proposed as high-performance alternatives to DSP processors. This paper quantitatively compares FPGA performance against DSP processors and ASICs using actual applications and existing CAD tools and devices. Performance measures were based on actual multiplier performance with FPGAs, DSP processors and ASICs. This study demonstrates that FPGAs can provide an order of magnitude b...

This paper gives the digit-serial DSP libraries used to implement the digit-serial DSP architecture for field programmable gate arrays (FPGAs) and compares schematic-based FPGA design with design based on logic synthesis for digit-serial DSP libraries. It describes the design of digit-serial addition/subtraction, multiplication and delay elements and indicates also how digit-serial FIR filter c...

A macro-programmable DSP architecture is presented, which is very well situated for the implementation of algorithms with regular data flow graphs, like FFTs. A smart grouping of the algorithm together with the macrocode concept reduce drastically the control and address generation overhead of the DSP and shorten the computation time. This is finally manifested in very low-power consumption, sm...

Unlike general-purpose processors, digital signal processors (DSP processors) are strongly application-dependent. To meet the needs for diverse applications, a wide variety of DSP processors based on different architectures ranging from the traditional to VLIW have been introduced to the market over the years. The functionality, performance, and cost of these processors vary over a wide range. ...
