Product Number: ADSP-21489

Software Version: CCES-2.10.1

Is there a efficient calculating interface for filter calculation? Usually, Multiply-Accumulate(MAC) is defined by platform to enhance calculating speed. If there is, I want to use it on platform 21489.

Hi ,

Can you please confirm that you have seen the below opcodes under SHARC+ Core Programming Reference help topic:
"opcode FLP_Mult, FXP_Add and FXP_MR_MR_Add_Mult in "CCES help"

If so, SHARC+ Core Programming Reference manual for ADSP-SC5xx and ADSP-215xx Processors.

We recommend to refer "Multifunction and Data Move" in the below linked PRM for ADSP-214xx processors
