Michael Tsiroulnikov, MIKET DSP Solutions

·        Methods of Efficient Testing and Debugging DSP   Programs

a. introduction

b. DSP programming as a multi-step procedure

    MATLAB -> Floating point C -> fixed point C >

    fixed point DSP C -> ASM

c. data structures, test oriented. No stack variables.

d. C/ASM function call conventions

e. program flow structuring, logic -> C, SP -> asm

g. divide & conquer. function size.

h. fixed point digital filter design potential flaws

        - FIR vs. IIR

        - min phase (polystab) FIR implementation of IIR

        - arbitrary waveform saturation test

        - etc

i. what is not possible to test

        - but what shall not be forgotten or overlooked

j. test case building

        - large signal,

        - max strength signal,

        - saturation,

        - stalling effect,

        - rounding,

        - pointer justification,

        - memory trash,

        - ! no interrupt/pipeline testing
