  1. 1. Towards Embedded Implementations of Multi-Armed Bandit Algorithms for Optimised Channel Selection

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Alex Kangas; [2021]
    Nyckelord :;

    Sammanfattning : The proliferation of Internet of Things increases the demand for achieving a high performance for embedded devices on the Internet. The IEEE 802.15.4 wireless network standard provides ultra low complexity, cost, power consumption and data rate for inexpensive devises, although it has problems such as external interference and multi-path fading.

  3. 2. FPGA Implementation of an Anonymization Algorithm

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Niklas Kjellman; Rehenuma Tarannum; [2020]
    Nyckelord :FPGA anonymization privacy anonymization filter spacial filter; Technology and Engineering;

    Sammanfattning : With the large amount of surveillance cameras in our public spaces there has been much discussion about their effects on privacy. Axis communications has an algorithm that tries to remedy this by making it hard to see who is in an image but still have it possible for a neural network to detect that there is a person present.

  4. 3. Bit-Vector Approximations of Floating-Point Arithmetic

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Joel Havermark; [2018]
    Nyckelord :;

    Sammanfattning : The use of floating-point numbers in safety-critical applications shows a need to efficiently and automatically reason about them. One approach is to use Satisfiability modulo theories (SMT). The naive approach to using SMT does not scale well. Previous work suggests approximations as a scalable solution. LÄS MER

  5. 4. ASIC implementation of LSTM neural network algorithm

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Michail Paschou; [2018]
    Nyckelord :Neural networks; LSTM; Long Short Term Memory; ASIC; VLSI; Neural networks; LSTM; Long Short Term Memory; ASIC; VLSI;

    Sammanfattning : LSTM neural networks have been used for speech recognition, image recognition and other artificial intelligence applications for many years. Most applications perform the LSTM algorithm and the required calculations on cloud computers. LÄS MER

  7. 5. Development of a microcontroller based DLCT end-point device

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Adam Simon Myrén von Schmalensee ; [2017]
    Nyckelord :;

    Sammanfattning : In this bachelor thesis the possibility of implementing a fully functioning Digital Signal Processing system based on the ARM-Cortex-m7 microcontroller from ST- microelectronics is investigated and implemented. The microcontroller is equipped with an Floating Point Unit, which resulted in the filter calculations being performed in floating-point arithmetic instead of fixed-point. LÄS MER
