DATA PROCESSOR AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To simplify the operation from the decision of a filter specification until its evaluation by using a GUI. SOLUTION: A user sets a filtering characteristics (frequency response) based on a GUI menu for setting the characteristic in S380. A computer generates a filter coefficient to realize the filtering characteristic in S382. The computer uses the filter characteristic to design an FIR filter in S384. The computer generates a program for a DSP to realize the designed FIR filter in S386. The computer downloads to the DSP in S388, and the DSP executes the program to apply filtering processing to image data. The computer describes the designed filter circuit by a hardware description language and provides an output.
