  1. 21. Pattern recognition with spiking neural networks and the ROLLS low-power online learning neuromorphic processor

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Andreas Ternstedt; [2017]
    Keywords : Pattern recognition; Spiking neural network; Neuromorphic hardware; Spike-based learning; Brain-inspired computing; Signal processing;

    Abstract : Online monitoring applications requiring advanced pattern recognition capabilities implemented in resource-constrained wireless sensor systems are challenging to construct using standard digital computers. An interesting alternative solution is to use a low-power neuromorphic processor like the ROLLS, with subthreshold mixed analog/digital circuits and online learning capabilities that approximate the behavior of real neurons and synapses.

    Keywords : Linux Device Driver; Scheduling; Interrupt Latencies; RTDM; SPI; XMOS; Audio Processing; Round-trip Latency; RTDM; Linuxdrivrutin; Schemaläggning; avbrottsfördröjning; interruptfördröjning; ljudbearbetning; tidsfördröjning; XMOS; SPI;

    Abstract : Professional audio processing systems such as digital musical instruments, audiomixers, etc. must operate with very tight constraints on overall processing latencyand CPU performance. READ MORE

  4. 23. Power-Aware Software Development For EMCA DSP

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Meishenglan Zhang; [2017]
    Keywords : ;

    Abstract : The advent of FinFET technology necessitates a shift towards early dynamic power awareness, not only for ASIC block designers but also for software engineers that develop code for those blocks. CMOS dynamic power is typically reduced by optimizing the RTL models in terms of switching activity and clock gating efficiency. READ MORE

  5. 24. Teaching Signals to Students: a Tool for Visualizing Concepts in Digital Signal Processing (DSP)

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Ebba Hermelin; Tobias Holmberg; Elsa Rick; [2017]
    Keywords : ;

    Abstract : Few Engineering students at Uppsala University choose to pursue their studies in signal processing, due to the level of difficulty within the subject. The main underlying problem is the students' trouble with understanding the behaviour of analog and digital filters, as well as the concept of stability. READ MORE

  6. 25. Development of a microcontroller based DLCT end-point device

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Adam Simon Myrén von Schmalensee ; [2017]
    Keywords : ;

    Abstract : 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. READ MORE
