The need for multimedia applications has prompted the addition of a SIMD instruction set On the one hand we have modern multimedia execution hardware and on the other we have the software and the general compilers which are not able to automatically exploit the multimedia instruction set. Our solution to these problems is to find statement candidates in the program written in the language C/C++ (as we mainly use this language), and to employ the SIMD instruction set in the easiest possible way. We proposed the algorithm for identifying candidates for parallel processing (ICPP) which is based on the syntax and semantic cheching of statements. We define the macro library MacroVect.c as the substitution for the discovered statement candidates.
