چکیده

In an effort to understand, experience and prove the benefits of automated SoC design, this report describes the specification modeling, design space exploration and implementation of a real world example using SpecC based System on Chip Environment (SCE). The report covers a complete description of developing the specification model of a MPEG-1 Layer 3 (MP3) audio decoder in SpecC language and the subsequent design space exploration and implementation using SCE. This report also attempts to improve the SoC design process by identifying the tasks in specification modeling that can be automated.

Evaluation of a new design approach for next generation mobile multi-media terminals

In this paper we present the results obtained sofar in an ongoing design pilot study for high-level system design. In order to gain insight and experience, we develop a mobile multi-media terminal using A|RT Designer by Adelante Technologies (former Frontier Design) [1]. This multi-media terminal supports a 4.8 kbps CELP codec and an MP3 decoder, giving voice and audio capabilities to the termi...

Implementation of AAC Encoder for Audio Broadcasting

MP3 is the popular audio coding standard. But now, a new higher quality audio coding standard Advanced Audio Coding (AAC) is proposed and widely used. The quantization/re-quantization is essential in both MP3 and AAC. It proposes a new high accuracy estimation algorithm for MP3 and MEPG-4 AAC audio coding. The algorithm can be applied not only for re-quantization process in decoder, but also fo...

Efficient Dataflow Representation of Mpeg-1 Audio (layer Iii) Decoder Algorithm with Controlled Global States

We present an efficient dataflow representation of MPEG-1 Audio (Layer III) Decoder (MP3) algorithm with controlled global states. Although dataflow graph has been a successful representation language for DSP applications, lack of global states makes it unsuitable to some applications that require periodic parameter update and dynamic behavior of function blocks. We show the global states can s...

Design, Implementation and Evaluation of two MP3 Hardware Decoder in Different Abstraction Levels using SystemC

The time-to-market requirements are forcing companies and designers to review their tools and methodologies. In this paper we have implemented, from scratch, two MP3 hardware decoders using SystemC, one at the RTL level and the other at the Behavioral level. We have validated them using the ISO reference specification and synthesized using TSMC 0.13um technology. To accomplish that, we took 6 d...

A low power VLSI implementation for variable length decoder in MPEG-1 layer III

MPEG Layer III (MP3) audio coding algorithm was a widely used audio coding standard. It involves several complex coding techniques and is therefore difficult to create an efficient architecture design. The variable length decoding was an important part, which needs great amount of search and memory read/write operations. In this paper a data driven variable length decoding algorithm is presente...
