SoC(System on Chip)의 발전은 현재 널리 쓰이는 기존의 설계 방법론으로는 해결될 수 없는 여러 가지 문제들을 생성하고 있다. 제품의 복잡도는 급격히 증가하는 반면 제품 수명은 지속적으로 감소하고 있으며, 기존 구현 기술의 향상만으로는 해결하기 쉽지 않은 VDSM (Very Deep Sub-Micron) 문제 또한 새로이 도출되고 있는 실정이다. 이러한 문제들은 적기에 시장에 제품을 출시하는 데에 많은 어려움을 끼치게 되기 때문에, 기존의 방법론을 뛰어 넘는 새로운 설계 방법론을 위한 많은 연구들이 활발히 진행되고 있다. 이러한 방법론 중 효율적인 한 방안으로 "재사용"의 개념이 대두되고 있으며, platform-based design은 이러한 재사용의 개념을 SoC 설계에 효율적으로 적용할 수 있는 방법으로 많은 관심을 받고 있다. 본 논문은 이러한 platform-based design의 최근 동향 및 현재 삼성전자에서 추진하고 있는 platform-based design에 대해 기술한다.

A stereo vision is able to build three-dimensional maps of its environment. It can provide much more complete information than a 2D image based vision but has to process, at least, that much more data. In the past decade, real-time stereo has become a reality. Some solutions are based on reconfigurable hardware and others rely on specialized hardware. However, they are designed for their own specific applications and are difficult to extend their functionalities. This paper describes a vision system based on a System on a Chip (SoC) platform. A real-time stereo image correlator is implemented using Sum of Absolute Difference (SAD) algorithm and is integrated into the vision system using AMBA bus protocol. Since the system is designed on a pre-verified platform it can be easily extended in its functionality increasing design productivity. Simulation results show that the vision system is suitable for various real-time applications.

Recently smart devices which combine traditional electronic devices and personal computers, such as smart phones and smart TV, have caught people's eyes from all over the world. A multi-media SoC platform which embeds not only a calculating processor but also an operating system could provide an user-customized environment of several types of communication methods to PC or Internet. In this paper, we describe a multi-functioning SoC platform with video, audio and other communicating protocols based on Core-A processor and AMBA buses. To verify the designed multi-media SoC platform, JPEG decoding and ADPCM encoding/decoding algorithms are applied on it and the final decoding results are confirmed by video monitors and audio speakers.

The requirement of a system-on-a-chip (SoC) design is increasing, which combines various and complex functional units on a single device. However, short time to market prohibits to release the device. To satisfy this shorter time-to-market, verification of both hardware and software at the same time is important. A virtual platform-based design method supports faster verification of these combined software and hardware by reusing pre-defined intellectual properties (IP). In this paper, we introduce the virtual platform-based design and redesign the existing ARM processor based S3C2440A system using the virtual platform-based method. In addtion, we implement and evaluate the performance of a JPEG decoder on the S3C2440A virtual platform. Furthermore, we introduce an optimized technique of the JPEG decoder using the ARM based inline assembly language, and then verify the performance improvement on the virtual platform. Such virtual platform-based design allows to verify both software and hardware at the same time and can meet the requirement of the shorter time-to-market.
