Honored Contributorhw multiplier for Cyclone
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...

Honored ContributorI got the tip to select a device with hw-multiblier-blocks (i.e. Cyclone-II) in the SoPC-Builder, generate the processor and prior to compile in Quartus change an option in the ???_mult_cell.vhd file - has someone done this successfully to get a working hw-multiplier for a Cyclone device?
Fast multiplication (and division) is very important for us because we use the Cyclone with Nios in a hard realtime system for high dynamic industrial motion control.

This replaces the divide custom instruction for Nios II.[/b] --- Quote End --- Where can I find this option? Thank you for your help Chris
