Difference between int32 and fixed point

6 views (last 30 days)
I am trying to program a FPGA using MATLAB and the HDL coder. So for the FPGA i need to have fixed point data types. If i am using data type of int32 is it fixed point? or i should use the fi object to convert my data to fixed point.

HDL Coder treats all integral types (both int and uint types) as the fixed point types that they are equivalent to. There is no need to convert integral types to fixed point.
For example, an int16 type is equivalent to fixdt(1,16,0), while an uint8 is equivalent to fixdt(0,8,0).
