is there a efficient interface to calculate the Multiply Accumulate(MAC)

i find the opcode FLP_Mult, FXP_Add and FXP_MR_MR_Add_Mult in "CCES help" . But did not find the source code file. Could you help me how to use them?

Hello borje,

I am moving this over to the SHARC forum where they can answer this question since they know that product.

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
