Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng): This work studies the applicability of adaptive timing systems into ultra-low power digital microelectronics to minimize the energy consumption.
The topic is studied by implementing a 32-bit RISC microprocessor equipped with timing error prevention logic.

The work consists of design, implementation and simulation phases, which are mainly conducted by using wide scale of Electronic Design Automation software.
The final layer mask is sent for manufacturing, which transforms it into a physical integrated circuit.
Based on simulation results, the design is able to save 34% of energy compared to a traditional system while maintaining reliable operation.
Abstract (fin): Tässä työssä tutkitaan adaptiivisen ajastuksen soveltuvuutta matalan tehonkulutuksen digitaaliseen mikroelektroniikkaan, jotta sen energiankäyttö voitaisiin minimoida.
Aihetta tutkitaan toteuttamalla 32-bittinen RISC -mikroprosessori, jossa hyödynnetään ajastusvirheen estävää logiikkaa.

Työ koostuu suunnittelusta, toteutuksesta ja simuloinnista, mitkä on tehty käyttämällä lukuisia EDA-ohjelmia.
Toteutettu työ lähetetään valmistettavaksi, jossa siitä tehdään fyysinen integroitu piiri.
Simulointitulosten perusteella työssä toteutettu järjestelmä toimii luotettavasti, ja kuluttaa 34 % vähemmän energiaa, kuin vastaava tavallinen toteutus.
