Flexible VLIW processor based on FPGA for real-time image processing
2011
Modern FPGA chips, with their larger memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high density FPGAs it is now possible to implement a high performance Very Long Instruction Word (VLIW) processor core in an FPGA. With VLIW architecture, the processor effectiveness depends on the ability of compilers to provide sufficient Instruction Level Parallelism (ILP) from program code. This paper describes research result about enabling the VLIW processor model for real-time processing applications by exploiting FPGA technology. Our goals are to keep the flexibility of processors in order to shorten the developm…
Vizuālais komforts sākumskolas interjerā
2022
Bakalaura darba temats bija „Vizuālais komforts sākumskolas interjerā“ un tā mērķis ir izveidot interjera dizaina projektu sākumskolai, radot vizuāli komfortablu mācību procesam atbilstošu vidi. Tika veikti pētījumi, kuros tika apspriestas tādas tēmas kā: vizuālais komforts izglītības iestāžu interjerā, apgaismojums izglītības iestāžu interjerā, skolu telpu funkcionālā plānojuma attīstības tendences, kas palīdzēja noteikt galvenos vizuālā komforta nosacījumus. 21. gadsimtā visā pasaulē ir notikušas ievērojamas izglītības modeļu transformācijas, lai nodrošinātu uz skolēniem vērstu pieeju mācībām. Interjera dizainam ir svarīga loma daudzos skolēnu mācīšanās aspektos. Efektīvs skolu dizains ra…
Priekšmetiskā pasaule J.Jaunsudrabiņa “Baltajā grāmatā” un “Zaļajā grāmatā”, un E.Birznieka-Upīša “Pastariņa dienasgrāmatā”. Motīva salīdzinājums
2018
Bakalaura darbā „Priekšmetiskā pasaule J. Jaunsudrabiņa „Baltajā grāmatā” un „Zaļajā grāmatā”, un E. Birznieka-Upīša „Pastariņa dienasgrāmatā”. Motīva salīdzinājums” ir raksturota priekšmetiskā pasaule J. Jaunsudrabiņa un E. Birznieka-Upīša autobiogrāfiskajos darbos, pievēršot uzmanību arī laikmeta kontekstam – 19. gs. otrajai pusei. No darbos ieraugāmajiem priekšmetiem raksturotas trīs priekšmetu grupas – ikdienā nepieciešamākās mēbeles (galds, gulta, krēsli u.c.), apgaismes priekšmeti un mūzikas instrumenti. Ar šo priekšmetu palīdzību iespējams raksturot darbos rādīto laikmetu, atklājot tā sadzīvi, kā arī tam raksturīgās izklaides iespējas. Darbā tiek veikts arī salīdzinājums, kuri priekš…

PNeuro: A scalable energy-efficient programmable hardware accelerator for neural networks
2018
Proceedings of a meeting held 19-23 March 2018, Dresden, Germany; International audience; Artificial intelligence and especially Machine Learning recently gained a lot of interest from the industry. Indeed, new generation of neural networks built with a large number of successive computing layers enables a large amount of new applications and services implemented from smart sensors to data centers. These Deep Neural Networks (DNN) can interpret signals to recognize objects or situations to drive decision processes. However, their integration into embedded systems remains challenging due to their high computing needs. This paper presents PNeuro, a scalable energy-efficient hardware accelerat…
Un algorithme de gestion de collision efficace pour un NoC déployé sur multi-FPGA
2014
International audience; Les plateformes multi-FPGA sont les solutions les plus prometteuses pour l'émulation de MPSoCs (Multi-Processor System-on-Chip) à base de NoC (Network-on-Chip). Le déploiement d'un NoC de grande taille sur une plateforme multi-FPGA nécessite la mise en place d'interfaces pour la communication inter-FPGA. Des goulots d'étranglements apparaissent, ralentissant fortement les performances du système. Dans ce travail, nous proposons un algorithme de gestion de collision permettant de supprimer ces goulots d'étranglement. L'algorithme de gestion de collision est basé sur l'algorithme de backoff utilisé dans les réseaux informatiques. L'architecture proposée est constituée …
A Portable Readout System for Microstrip Silicon Sensors (ALIBAVA)
2009
A readout system for microstrip silicon sensors has been developed. This system is able to measure the collected charge in one or two microstrip silicon sensors by reading out all the channels of the sensor(s), up to 256. The system can operate either with non-irradiated and irradiated sensors as well as with n-type and p-type microstrip silicon sensors. Heavily irradiated sensors will be used at the Super Large Hadron Collider, so this system can be used to research the performance of microstrip silicon sensors in conditions as similar as possible to the Super Large Hadron Collider operating conditions. The system has two main parts: a hardware part and a software part. The hardware part a…
The Mu3e Data Acquisition
2020
The Mu3e experiment aims to find or exclude the lepton flavour violating decay $\mu^+\to e^+e^-e^+$ with a sensitivity of one in 10$^{16}$ muon decays. The first phase of the experiment is currently under construction at the Paul Scherrer Institute (PSI, Switzerland), where beams with up to 10$^8$ muons per second are available. The detector will consist of an ultra-thin pixel tracker made from High-Voltage Monolithic Active Pixel Sensors (HV-MAPS), complemented by scintillating tiles and fibres for precise timing measurements. The experiment produces about 100 Gbit/s of zero-suppressed data which are transported to a filter farm using a network of FPGAs and fast optical links. On the filte…

Ms. 930a, Nr. 8, Bl. 22r-23v Böttiger, Karl August. Brief an Garlieb H. Merkel, Weimar, d[en] 13. November 1797 Autora rokraksts / Autograph, vācu, angļu un latīņu val. / Deutsch, Englisch und Latein [4] lpp. / S. Attēlu numuri / Bildnummern: 930a-008-1 – 930a-008-4 Der Verfasser nennt in diesem inhaltsreichen Brief zahlreiche Namen und hält nicht nur die Verbindung mit Merkel, die aus dessen erstem Aufenthalt in Weimar resultierte, aufrecht, sondern gibt ihm weitere Hinweise und Empfehlung für seinen weiteren Aufenthalt in Dänemark. So rät er zur Übersetzung dreier Romane aus dem Englischen, darunter Jane Wests „A gossip's story“ (London 1796). Ferner bittet der Verfasser Merkel um Gefälli…
In human and rat lung membranes [35s]GTPγS binding is a tool for pharmacological characterization of G protein-coupled devucleotide receptors
1999
The P2Y receptor family is activated by extracellular nucleotides such as ATP and UTP. P2Y receptors regulate physiological functions in numerous cell types. In lung, the P2Y2 receptor subtype plays a role in controlling Cl- and fluid transport. Besides ATP or UTP, also diadenosine tetraphosphate (Ap4A), a stable nucleotide, seems to be of physiological importance. In membrane preparations from human and rat lung we applied several diadenosine polyphosphates to investigate whether they act as agonists for G protein-coupled receptors. We assessed this by determining the stimulation of [35S]GTPgammaS binding. Stimulation of [35S]GTPgammaS binding to G proteins has already been successfully ap…
