An FPGA-based Target Acquisition System

Marschner, Alexander R. 09 January 2008 (has links)
This work describes the development of an image processing algorithm, the implementation of that algorithm as both a strictly hardware design and as a multi-core software design, and the side-by-side comparison of the two implementations. In the course of creating the multi-core software design, several improvements are made to the OpenFire soft core micro-processor that is used to create the multi-core network. The hardware and multi-core software implementations of the image processing algorithm are compared side-by-side in an FPGA-based test platform. Results show that although the strictly hardware implementation leads in terms of lower power consumption and very low area consumption, modification of and programming for the multi-core software implementation is simpler to perform. / Master of Science

Τεχνολογίες instant messaging σε επίπεδο πελάτη και εξυπηρετητή με την χρήση της υπηρεσίας PubSub

Τόκης, Θεόδωρος 17 February 2015 (has links)
Σκοπός μας είναι να μελετήσουμε, αναπτύξουμε και να υλοποιήσουμε μία υπηρεσία PubSub με την βοήθεια του εργαλείου ανοικτού κώδικα Agsxmpp SDK. Η υπηρεσία αυτή θα είναι διαθέσιμη σε όλους τους χρήστες ενός συστήματος και θα υπάρχει η δυνατότητα στον καθένα να δημιουργεί αναρίθμητα θεματικά «κανάλια» μηνυμάτων κάθε τύπου. Κάθε χρήστης θα έχει δικαίωμα εγγραφής σε ένα τέτοιο «κανάλι» και έτσι θα έχει την δυνατότητα να λαμβάνει τα μηνύματα και τις ανανεώσεις που δημοσιεύονται σε αυτό. Σαν «κανάλια» ορίζουμε τα Nodes, η εγγραφή ορίζεται ως subscribe, η δημοσίευση ως publish και τέλος την ειδοποίηση / παραλαβή ως notification. / Our aim is to study, develop and implement a service with PubSub the help of open source tools Agsxmpp SDK. The service will be available to all users of a system and possible for anyone to create numerous thematic "Channels" each message type. Each user will have the right recording in such a "channel" and thus is able to receive messages and updates posted on this. like "Channels" are defined as Nodes, the record is defined as subscribe, the publication to publish and finally notification / receipt as notification.
