This paper presents a programmable System-On-a-chip for various embedded applications that need Neural Network computations. The system is fully implemented into Field-Programmable Gate Array (FPGA) based prototyping platform. The SoC consists of an embedded processor core and a reconfigurable hardware accelerator for neural computations. The performance of the SoC is evaluated using real image processing applications, such as optical character recognition (OCR) system.

In this paper a GPS receiver is developed using commercial chipsets. GP2010 RF front end and GP2021 Multi-channel correlator of GEC PLESSY are adapted in designing the receiver hardware. MC 68340 is used for controlling the correlator GP2021 and implementing the navigation processing. Also presented are some test results of the developed receiver whose software has an interrupt driven structure rather than common real-time kernel based structure.

To monitor abnormal state of rotary compressor, methods for acquisition and processing of Acoustic Emission(AE) signal are arranged and optimal AE parameter for monitoring is determined. The detecting method of abnormal compressor in real time is suggested and special-purpose minitoring system which can be applied to automatic manufacturing line is developed using one-chip microprocessor in low cost.

General trend in electronics industry towards multimedia in the 21 century is presented here. All equipments require fast graphic processing together with thin and lightweight assembly technology. In Japan, CSP was developed and applied to mobile equipments for several years, and recently stacked die assembly technology is being developed. In addition, so-called flip chip technology is also being developed and which is applied to MCP and MCM little by little these days. Here current packaging technology in Japan is presented including above.

Introduction of digital communication network such as Integrated Services Digital Networks(ISDN) and digital storage media have rapidly developed. Due to a large amount of image data, compression is the key techniques in still image and video using digital signal processing for transmitting and storing. Digital image compression provides solutions for various image applications that represent digital image requiring a large amount of data. In this paper, the proposed DWT(Discrete Wavelet Transform) filter bank is consisted of simple architecture, but it is efficiently designed that a user obtain a wanted compression rate as only input parameter. If it is implemented by FPGA chip, the designed encoder operates in 12MHz.

A realization of a conventional cryptosystem for personal computers using the DSP56001 digital signal processing chip is presented. An improved Lucifer-type algorithm is employed to encrypt, and executed in the DSP56001. The Diffie-Hellman method is employed to generate and distribute the key. The implemented hoard can be plugged in the I/O port of personal computers.

현대 산업화에 있어 가장 비중 있는 분야는 바로 자동화이며, 섬유기계의 자동화야 말로 그 정밀도와 내구성면에서 볼 때 가장 발달된 첨단기술중의 하나라고 할 수 있다. 이러한 자동화의 첫걸음은 시스템의 현 상태를 정확하고도 빨리 이해하는 기술, 즉 모니터링 기술이라 해도 과언이 아니다. 이 모니터링 기술은 데이터의 수집과 분석으로 이루어지며 각각은 하드웨어적, 소프트웨어적 디지털 신호처리(Digital Signal Processing : DSP) 기술에 대찬 의존도를 높여가고 있다. (중략)
