Recently, various special purpose processors have been developed and are frequently being used for different specialized tasks. Prominent among these are the communication processors, which are generally used within an embedded system environment. Such processors can run relatively advanced and general purpose operating systems such as uCLinux, which is a freely available embedded Linux distribution. In this work, a prototype SoHo (Small office / Home office) router is designed and implemented using Motorola MCF5272 as the core communication processor and uCLinux as the operating system. The implementation relies purely on the existing hardware resources of an available development board and the publicly available open source utilities of uCLinux. The overall development process provides an embedded system implementation and configuration example.

A New Estimation Technique for AR(1) Model with Long-tailed Symmetric Innovations Akkaya, Ayşen (null; 2017-09-17) In recent years, it is seen in many time series applications that innovations are non-normal. In this situation, it is known that the least squares (LS) estimators are neither efficient nor robust and maximum likelihood (ML) estimators can only be obtained numerically which might be problematic. The estimation problem is considered newly through different distributions by the use of modified maximum likelihood (MML) estimation technique which assumes the shape parameter to be known. This becomes a drawback ...
Use of spatial four-bar mechanism for the synthesis of mechanisms with large dwell Söylemez, Eres; Parlaktas, V (2004-04-04) In several design applications there is a need for mechanisms having long periods of dwell. If the output is to remain completely stationary cam, geneva or intermittent gear mechanisms are used. When an approximate dwell is sufficient, this is usually achieved by mechanisms with lower kinematic pairs or with cycloidal motion mechanisms utilizing gear pairs. There exists several examples in the literature where a cam is conveniently replaced by a six-link planar dwell mechanism. However, in cases where large...
A longest path problem for evaluating the worst case packet delay of switched ethernet Schmidt, Klaus Verner; Schmidt, Şenan Ece (2010-07-09) In the recent years, the use of real-time Ethernet protocols becomes more and more relevant for time-critical networked industrial applications. In this context, this paper presents a method to compute the worst-case packet delays on switched Ethernet. Based on an evaluation of the packet delays at each switch port and the network topology, we construct a weighted directed graph that allows to find the worst-case end-to-end packet delay by solving a conventional longest-path problem.
INVESTIGATION OF NEW ARCHITECTURAL FEATURES TO SUPPORT PERFORMANCE IMPROVEMENT IN EMBEDDED PROCESSORS Othman, Ahmad; Fahrioğlu, Murat; Yemişcioğlu, Gürtaç; Electrical and Electronics Engineering (2022-8) Recent advances in process automation, wireless sensor networks, and machine-to-machine (M2M) interfaces have caused embedded systems to be a blooming computing segment, with significant research focus on performance and energy efficiency. The embedded systems market witnessed enormous growth over the past decades and is foreknown to be boosted in the upcoming years. It has become harder to scale CMOS technologies compared to past and get performance and energy benefits through technology and circuits. Ther...
A VERSATILE MICROCOMPUTER INTERFACE AND PERIPHERAL DEVICES - AN APPLICATION IN DEUTERIUM LAMP BACKGROUND CORRECTION GRAPHITE-FURNACE ATOMIC-ABSORPTION SPECTROMETRY GOKMEN, A; YALCIN, S (1992-01-01) A versatile interface card for Apple IIe computer and various peripheral devices are designed to control instruments which generates transient signals like in graphite furnace atomic spectrometer. The interface card consists of a multiplexed analog-to-digital converter, a digital-to-analog converter, and a timer/counter chip. The timer/counter chip with 16 built-in registers can be programmed in many modes which provides a time base for real-time measurements. A stepper motor runs under the control of ti...
