As I understand it, you are inquiring for IP which could implement matrix multiplication fixed point for CV devices. As I search through the IP list, sorry as there is not specific IP for this. You might need to code the module using user logic. Sorry for the inconvenience.
I already understand that I should write this module by myself.
To write module for fix point number mathematics I should use specific Library that support this calculations.
Could you help me to find this library that supported in CYCLONE 5 and PRIME STANDARD edition of QUARTUS.
