The purpose of this paper is to introduce a design method of an embedded advanced RISC machines (ARM) hardware circuit using the microprocessor S3C44B0 as a core according to a testing principle of wiring harness.

The microprocessor module is designed with the S3C44B0 of Samsung Corp. The microprocessor send test instructions to the wiring harness circuit, receive and store the test data, get and display the test results by the liquid crystal display, and the wiring harness testing circuit is implemented by complex programmable logic device. The uClinux operating system is transplanted into the ARM hardware platform, and the developing and loading code of the uClinux device driver and a basic flow chart is given.

The combination of S3C44B0 and uClinux embedded microprocessors achieved a powerful wiring harness tester driver development. This structure leads to a flexible configuration and convenient extension.

A Linux development environment is established and the device drivers compiled into the kernel. But the development of the application program and the user operating interface of the wiring harness have not been completed yet.

After the development of the application program and the user operating interface of the wiring harness, this device should be able to find practical application in the industry.

This wiring harness tester can detect different failures at the first time through the wiring harness on‐test to ensure the product quality, reduce the labor intensity, improve the working efficiency, and enhance the test accurately.

One of the fashionable talking points of the moment is the electronic microprocessor. It has suddenly become news. The government is to spend an initial £50 million of taxpayers' money on establishing a Microelectronics Unit; domestic appliances are now advertised as ‘containing MPUs — an electronic marvel with many thousands of transistors in a minute space’. Already, in the United States, a huge complex of companies who design and manufacture MPUs and similar devices has assembled in what is known as Silicon Valley (actually the Santa Clara Valley) in the same way that cars gravitated to Detroit and music to Memphis. Machines are in operation, and many more are being designed, which can simulate the thinking process and make decisions on the basis of data fed to them or which they can call for. Machines that think can be seen as a potential threat to some workers and fears are already being expressed about the effect of the MPU revolution on the work situation and on unemployment in particular. There can be no doubt that most jobs as we know them today will be changed, some of them out of all recognition, by this latest innovation — the MPU Revolution.

The British Microprocessor Competion has been launched by its joint sponsors—the National Research Development Corporation (NRDC) and The National Computing Centre Ltd. (NCC).

Microcomputer systems which are the most relevant to today′s manager are the prime focus. New developments during the last 18 months are given priority. Microprocessors used in recent microcomputer systems in relation to the RISC and CISC technologies are discussed. Networking and standardisation, two major areas of development, are described, along with the hardware, software and peripherals of microsystems. Finally, the application to managers is analysed.

Three important problems face managers in coming to terms with the advent of microprocessors. Microprocessors offer radical new possibilities for designing products and systems but the latter need to be conceptualised as wholes rather than seen as series of discreet but interconnected sub‐systems. The second difficulty lies in evaluating and choosing a CAD system in that confining the evaluation to the implications for the drawing office can result in failure to consider factors vital to the company's future. The third problem lies in the implications of automation for production. The benefits spill out beyond the boundaries of the department in which a particular piece of capital equipment is installed, emphasising the need for a strategic approach.

The handling of initially disordered mechanical parts with a robot manipulator needs some procedure for orientating these parts. A simple microprocessor‐controlled TV‐sensor which enables an industrial robot to perform this function by measurement of orientation and position of the parts is described. Constraining the parts to a finite number of stable positions by mechanical devices preceding the visual sensor, restriction to binary images, processing of only a few information carrying TV‐lines and a simple recognition algorithm lead to an easily programmable microprocessor‐controlled visual sensor which accomplishes all practical requirements of flexibility, high speed, low memory size and low costs.

Rather than organize as traditional firms, many of today’s companies organize as platforms that sit at the nexus of multiple exchange and production relationships. This chapter considers a most basic question of organization in platform contexts: the choice of boundaries. Herein, I investigate how classical economic theories of firm boundaries apply to platform-based organization and empirically study how executives made boundary choices in response to changing market and technical challenges in the early mobile computing industry (the predecessor to today’s smartphones). Rather than a strict or unavoidable tradeoff between “openness-versus-control,” most successful platform owners chose their boundaries in a way to simultaneously open-up to outside developers while maintaining coordination across the entire system.

The purpose of this study is to extend a sensitivity-based reliability technique for the processors deployed in industrial drive (ID).

The processor provides flexible operation, re-configurability, and adaptable compatibility in industrial motor drive system. A sensitivity-based model allows a robust tool for validating the system design. Sensitivity is the probability of a partial failure rate for a distributed variable; sensitivity and failure rates are also complementary. Conversely, traditional power electronic components reliability estimating standards have overlooked it, and it is essential to update them to account for the sensitivity parameter. A new sensitivity-based reliability prediction methodology for a typical 32-bit microprocessor operating at 30ºC deployed in ID is presented to fill this gap. The proposed techniques are compared with the estimated processor reliability values obtained from various reliability standards using the validated advanced logistics development tool. The main contribution of this work is to provide a sensitivity extended reliability method over the conventional method directing toward improving reliability, availability, and maintainability in the design of ID.

The analysis shows that the sensitivity of the processor’s circuit increases due to increases in complexity of the system by reducing the overall mean time between failure upon comparing among conventional reliability standards.

The significance of this paper lies in the overall, sensitivity-based reliability technique for processors in comparison to the traditional reliability complexity in IDs.

The advantages in the use of microprocessors are by now very well documented and these devices are used the world over in a multitude of roles. In many cases, they are underused regarding their design capacity, but still have the large advantage of enabling manufactering time and complexity to be much reduced keeping costs down. Thus we even see them used in relatively simple household appliances and childrens toys — all of which has contributed in the past to demand exceeding supply and subsequent cost escalation. Use of a microprocessor does not of itself, necessarily produce a better system, other than reducing manufacturing complexity. The device must be built into a system able to use if efficiently and the whole must be programmed correctly for the planned work. In jargon: ‘the hardware must be able to use the software and the software must be designed for the requirement’.

This paper describes the simulation of a nearest neighbour searching algorithm for document retrieval using a pool of microprocessors. The documents in a database are organised in a multi‐dimensional binary search tree, and the algorithm identifies the nearest neighbour for a query by a backtracking search of this tree. Three techniques are described which allow parallel searching of the tree. A PASCAL‐based, general purpose simulation system is used to simulate these techniques, using a pool of Transputer‐like microprocessors with three standard document test collections. The degree of speed‐up and processor utilisation obtained is shown to be strongly dependent upon the characteristics of the documents and queries used. The results support the use of pooled microprocessor systems for searching applications in information retrieval.
