Area of 16bit floating-point Gemmini

[edward mulier]

In the 2021 Gemmini paper (https://arxiv.org/pdf/1911.09925) the total area is presented to be  1 029 000 um^2 for a 22nm 1GHz default (16x16 systolic array) Gemmini configuration. 

However this is(if I'm not mistaken) for the INT8 precision for inputs and weights. 

My question is: what is the area of a 16-bit floating-point configuration, keeping everything else default?

So using the same systolic array size(16x16), same scratchpad sizes, same Rocket single-core CPU, but just changing the systolic array to support 16bit floating point numbers instead of 8bit integers?

I couldn't find any papers that report on area for a floating-point Gemmini configuration.

If there are papers, or people who have an estimation on the area increase, feel free to point me in the right direction.

Best regards,

Edward
