I want to mention a programming question about ADSP21489

Because of the requirements of the algorithm project code,I want to apply for a memory block with a length of 50574, the code is:

void* trp;

trp = (void*) malloc(50574);

I found that the application was unsuccessful, so I would like to ask how can I solve it? Or how can I store it in SDRAM? How should the code be written?

Thank you.
