Abstract:The aim of the thesis was to optimize the UWB first path search algorithm performance on a dedicated DSP. Development was focused on enabling various optimizations tech- niques of the DSP architecture. Insights into how the CIR is correlated, how the FP algo- rithm determines the actual FP are presented. The purpose of optimizing the FP algorithm was to improve the performance and lower the power consumption of the UWB system. The highly optimized DSP architecture contains numerous optimization techniques that needed to be discovered. With the optimization techniques provided by the DSP architec- ture, we were able to boost the FP algorithm performance by a significant amount, with potential for further enhancements.

Title:Optimizacija delovanja UWB algoritma za iskanje prve poti na namenskem DSP-ju
Abstract:Magistrsko delo opisuje postopek optimizacije delovanja algoritma UWB prve poti na namenskem digitalnem signalnem procesorju. Algoritem prve poti je namenjen iskanju prvega signala, ki mora biti višji od definiranega praga šuma in je potencialen kandidat za izračun časa preleta, ki je pomemben za izračun razdalje med napravami. Običajno je signal, ki ima največjo moč tudi signal prve poti, vendar se lahko zgodi, da je moč signala prve poti manjša od moč signala, ki je prepotoval daljšo razdaljo, predvsem v primerih, ko si napravi UWB izmenjujeta pakete UWB brez neposredne vidne linije. Zato je pomembno dobro opredeliti metode, ki omogočajo prepoznavo signala prve poti, to so običajno zaupni podatki podjetij, ki razvijajo take sisteme. Ugotovili smo, da so optimizacije pokazale visoko učinkovitost izvedbe algoritma prve poti. Razvijanje programske kode s poglobljenim poznavanjem procesorske arhitekture privede do učinkovitejšega procesiranja, kar posledično omogoča znatno zmanjšanje porabe električne energije. Podali smo možnosti za izboljšanje učinkovitosti, morebitne probleme in napotke.
