| Abstract: | The assembly language of TMS320C54x DSP is usually conjunct with C code when the DSP projects are developed in order to make full use of the advantage of these two types of language. The approach and strategy of the mixed language programming based on TMS320C54x DSP are introduced in this paper and the DSP interrupt function based on C language is proposed in detail. The decomposition algorithm of the quadratic B spline wavelet is taken as an example to illustrate the method of mixed language programming, the C programs and the assembly language codes are also listed at the end of this paper. |
