A modular microcomputer system based on the Intel 8080 microprocessor is designed. Each module communicate via common bus system. The different modules can be placed anywhere on the bus. Address for memory and I/O modules are determined by switch registers situated on the modules. The system is intended to be used as a base equipment for continuing study, expansion, development and for teaching students.

With the development of IT and digital camera technology, diverse applications of image processing services are becoming available. In this paper, in order to ultimately automate parking management system, we designed and implemented a system for recognizing vehicle license plates that show vehicles' unique numbers by using EmguCV which shows optimized performance on Intel-based environment. We also implemented UI for administrators to easily manage the entire system by utilizing.

Three-dimensional integration technology results in area savings, platform power savings, and an increase in performance. Through-silicon via (TSV) assembly and manufacturing processes can potentially introduce defects. This may result in increases in manufacturing and test costs and will cause a yield problem. To improve the yield, spare TSVs can be included to repair defective TSVs. This paper proposes a new built-in self-test feature to identify defective TSV channels. For defective TSVs, this paper also introduces dynamic self-repair architectures using code-based and hardware-mapping based repair.

With the development of nonvolatile memory technology, Intel has released the Optane datacenter persistent memory module (DCPMM) that can be deployed in the dual in-line memory module. The results of research and experiments on Optane DCPMMs are significantly different from the anticipated results in previous studies through emulation. The DCPMM can be used in two different modes, namely, memory mode (similar to volatile DRAM: Dynamic Random Access Memory) and app direct mode (similar to file storage). It has buffers in 256-byte granularity; this is four times the CPU (Central Processing Unit) cache line (i.e., 64 bytes). However, these properties are not easy to use correctly, and the incorrect use of these properties may result in performance degradation. Optane has the same characteristics of DRAM and storage devices. To take advantage of the performance characteristics of this device, operating systems and applications require new approaches. However, this change in computing environments will require a significant number of researches in the future.

로봇산업과 정밀기계산업을 포함한 많은 산입현장에서 서보모터를 이용한 기기 및 응용제품들이 다양하게 활용되고 있다. 이때 현장의 특성에 맞는 제어 시스템의 개발을 위해서나 사용 현장에서의 모터 동작 모니터링을 위해 제어가 편리한 사용자 친화적인 모니터링 시스템을 활용 한다면 업무 효율을 향상 시킬 수 잇다. 본 논문에서 개발한 DC모터 제어 및 모니터링 시스템은 임베디드 시스템을 기반으로 설계되었다. 이 시스템은 Intel PXA255 CPU를 장착하고 리눅스를 OS로 사용하였으며, 블루투스를 이용한 무선통신으로 모터 드라이버와 모니터링 및 제어에 필요한 데이터를 주고 받는다. 또한, 사용자 친화적인 GUI(Graphical User Interface)로 구성되어 조작 및 관리가 편리하다. 임베디드 기기의 특성상 시스템의 규모가 작고 무선 통신이 가능한 블루투스를 사용하였기 때문에 휴대성과 이동성이 뛰어나다는 장점이 있다. 이는 업무 효율의 향상을 기대할 수 있게 한다.

This report introduces a faster parallel LU decomposi-tion algorithm that gives a speedup almost equal to the number of nodes used. The new algorithm takes an advantage of an important C feature that lays out a matrix using a row major scheme and is based on the currently widely used LU decomposition algorithm with one major modification to eliminate most of the communication overhead. Empirical results are included in this report. For example solving a dense matrix that contains 100,000,000 elements gives a speedup of 50 when executed on 50 nodes of an intel Paragon in parallel.

In this paper, image detection and recognition algorithms are studied with respect to embedded carrier system. There are many suggested techniques to detect and recognize objects. But they have the propensity to need much calculation for high hit rate. Advanced and modified method needs to study for embedded systems that low power consumption and real time response are requested. The proposed methods were implemented using Intel(R) Open Source Computer Vision Library provided by Intel Corporation. And they run and tested on embedded system using a ARM920T processor by cross-compiling. They showed 1.6sec response time and 95% hit rate and supported the automated moving carrier system smoothly.

By using the RAPHAEL 3D inductance calculation program RI3, the PGA package inductance values of INTEL i486 microprocessor have been extracted. The lead frame layouts are drawn using the mentor Boardstation and the output files are converted into the RI3 program input format of RAPHAEL. The power and ground planes of the PGA package are modeled y grid-line structures of single bars. The capacitance valuse of signal lines have been clalculated by using the RAPHAEL 2D/3D capacitance extraction program. The extraced L, C, R values have been converted into the SPICE netlist formats with lumped circuit model for future use in the signal ingegrity analysis.
