What multiplier can do 16 bit by 26 bit?

Hi, 

 

I am new to Altera. I read an article on division with APEX, which was an old device. It said: 

 

On an Altera APEX device, when combining the LUT and multiplier into a single division module, a 16 bit by 26 bit multiplier consumes 838 logic elements (LEs), operating at 25 MHz clock frequency and total memory consumption of 53248 memory bits for the specific target FPGA device 

 

 

I know modern FPGA has 18X18 multipliers. The above statements look like a memory lookup table multiplier? How to implement it in new FPGA?  

 

Thanks,

Im not sure what the question is. You would implement it that same way as the apex if you wanted a memory multiplier. But now its easiest just to do the multiply in hdl and let the compiler infer the hardware.
