Abstract
U ovom radu se proučava primjena sustava temeljenog na procesoru koji je namijenjen radu s podacima nepomičnog zareza, implementacijom algoritma određivanja fazne razlike ultrazvučnog signala. Najprije se rješava dvosmislenost registriranja faze harmoničnog signala koji na prijemnik dolazi zakašnjen za iznos višestukog perioda primjenjujući više-harmonijski signal s većim zajedničkim periodom od pojedinačnih. Zatim se matematički proučavaju diskretne Fourieove transformacije. Odabran je Gertzelov algoritam jer nema potrebe za računanjem svih kompleksnih uzoraka spektra. U daljnjem razvoju algoritma proučavaju se ograničenja i specifičnosti frakcionalne aritmetike, te se s obzirom na to isti ostvaruje u C-u. Jedna od posljedica tog pristupa je potreba za arkus tangens funkcijom dobivenom polinomijalnom aproksimacijom. Korišteni razvojni sustav je eZdsp TMS320VC5505.
Abstract (english)
In this paper, fixed-point based processor development kit is studied trough implementation of phase-difference ultrasonic signal algorithm. First the phase-differece ambiguity of harmonic signal is managed using multy-harmonic signal. The discrete Fourier transforms and their use are discussed. Goerzel algorithm was chosen for that matter becouse of its optimal computational complexity for this application. In algorithm development, limitations and specific features of fractional arithmetics are analyzed. Coding was done using C-language in Code Composer Studio v4. One of the consequences of this approach is a need for arcus tangens polinomial approximation function.The development kit of interest is eZds TMS320VC5505.
