With NIOS-1 i could select three implementations for multiplications (sw, mul_step, mul). In Nios-2 this feature is complety missing. Is there any way to tell the SOPC-Builder for NIOS-2 to integrate...

--- Quote Start --- I don't know if Cyclone II would have it in the GUI but it shows up as a check box under the "f" core.[/b] --- Quote End --- This is true if I select a Stratix device in "Target Device Family". But for a Cyclone/CycloneII Devices the checkbox is hidden. At least for my SOPC-Builder 4.1 Build 207. We decided to use a custom instruction for multiplication and division until this options is available in a future release. Is there any way to tell the compiler to use such an instruction instead the standart mul?
