In this paper, we briefly introduce the AVS-M, show the SATD function definition and the role of it. And then, we optimize the SATD function in AVS-M in four parts: expand cycle, use macro definition to the absolute value calculation, use the C library function instead of macro definition, merger the final step of Hadamard_Transform. Through optimization, coding speed increased from 1.15 frame/sec to 1.32 frame/sec.
