vector_add example - Not using DSP blocks

[Altera_Forum]

Hello Everyone, 

 I am trying to analyze the resource usage of opencl "vector_add.cl" example.   aoc -c vector_add.cl -report  +--------------------------------------------------------------------+ ; Estimated Resource Usage Summary ; +----------------------------------------+---------------------------+ ; Resource + Usage ; +----------------------------------------+---------------------------+ ; Logic utilization ; 17% ; ; ALUTs ; 12% ; ; Dedicated logic registers ; 7% ; ; Memory blocks ; 12% ; ; DSP blocks ; 0% ; +----------------------------------------+---------------------------;  From this report, it is not using any of the DSP blocks available in FPGA. How to use DSP blocks?  Thanks Pavan

The DSP blocks on your FPGA do not support floating-point addition and hence, they cannot be used in the vector add example. Only the DSPs in Arria 10 and above support floating-point addition.
