I wonder if there is place for a "decision operator". (search terms: FPGA, evolvable hardware, Xilinx, PLB, LUT, NESW)
dop:| 0 1 2 3 4 5 6 7 8 9 A B C D E F ----+-------------------------------- 0 0 | 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 0 1 | 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 1 0 | 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1 1 1 | 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 So for two boolean inputs, "&" is an alias of dop(1), "|" is an alias of dop(0x07), "^" is an alias of dop(0b0110). (1,0).dop(7) returns 1 because (1 | 0) == 1 (4,3).dop(7) returns 7 because (4 | 3) == 7 ("A","F").dop(7) returns "G" because ("A" | "F") eq "G" (1,1,1).dop(0b01101001) returns 1 because (1^1^1) == 1 -- Ruud
