Honored Contributorhow I can create a custom instruction to manage operations on vectors
hi, I'm trying to write a VHDL component that makes a multiplication between two matrices or vectors. the component will be a custom instruction that I would use in nios in the following way ...

Honored ContributorEasily :-)
Also (IIRC) qsys will directly expose the 2nd port of a memory block - so you can directly attach external VHDL to it. Or you write your own Avalon slave interface for the memory block inside your VHDL. In the latter case you may not be able to use the more efficient 'tightly coupled data' interface for the memory block (although that would also proclude DMA access to it).
