This is a simplification in the blog post: each activation doesn't map one-to-one onto a physical FPGA LUT primitive, but is instead represented as a "logical LUT" (L-LUT) that Vivado synthesizes into distributed RAM. These L-LUTs map very naturally to FPGA fabric (as compared to multiply-accumulate operations), making them a very useful implementation-level abstraction. |
