I understand your assumptions now. You’re saying SP mult is by convention twice the flops for half the area, and I was talking about same flops for one fourth the area. It’s a choice. There might be a current convention, but regardless, the sum total is a factor of 4 cost for each double precision mult op compared to single. Frame it how you like, divvy the cost up different ways, the DP mult cost is still 4x SP. Aaaanyway... that does answer my question & confirm what I thought, thank you for explaining and clarifying the convention.
