چکیده

This paper summarizes our work adapting a recursive digital resonator for use on sixteen-bit fixed-point hardware. The modified oscillator is a two-pole filter with error properties expressly matched to use in the range of frequencies relevant to additive synthesis of digital audio. We present the algorithm, error analysis, performance analysis, and measurements of an implementation on a fixed-point vector microprocessor system.

A Comparison Between Processor Architectures for Multimedia Applications

The efficient processing of MultiMedia Applications (MMAs) is currently one of the main bottlenecks in the media processing field. Many architectures have been proposed for processing MMAs such as VLIW, superscalar (general-purpose processor enhanced with a multimedia extension such as MMX), vector architectures, SIMD architectures, and reconfigurable computing devices. The question then arises...

Evaluating Signal Processing and Multimedia Applications on SIMD, VLIW and Superscalar Architectures

This paper aims to provide a quantitative understanding of the performance of DSP and multimedia applications on very long instruction word (VLIW), single instruction multiple data (SIMD), and superscalar processors. We evaluate the performance of the VLIW paradigm using Texas Instruments Inc.’s TMS320C62xx processor and the SIMD paradigm using Intel’s Pentium II processor (with MMX) on a set o...

21 Processor Architectures For

In this chapter, we present contemporary VLSI processor architectures that support multimedia applications. We classified these processors into two groups: dedicated multimedia processors, which perform dedicated multimedia functions, such as MPEG encoding or decoding, and general-purpose processors that provide support for multimedia. Dedicated multimedia processors use either function-specifi...

EE 382C Embedded Software Systems Project Proposal

Objective: The goal of this project is to evaluate the effectiveness of two different techniques for exploiting the Instruction Level Parallelism (ILP) available in Digital Signal Processing (DSP) and Multimedia applications. VLIW (Very Long Instruction Word) architectures have multiple functional units to take advantage of such a parallelism, while the SIMD (Single Instruction Multiple Data) a...

Superword Processors 22 June 2001

This paper introduces the concept of a superword processor, a style of computer-architecture design in which a traditional processor datapath is replicated in SIMD fashion, transforming each machine instruction into a SIMD equivalent. Superword techniques are appealing because they require minimal changes to an existing design, offer backward compatibility with an existing ISA, and offer large ...
