-- 1 . Dont register them: But for there is going to be a maximun number of columns where porpagation times are going to be |
-- too high in order to substain a one clock upwards pipe. It depends upon the platform you are using how many columns you can implement in the row without registering them. |

-- Ray Difussion Pipe Longitude ( |
-- Row Ray Difussion Time ( RRDT ) in clks: 2 + log 2 (Number of Columns) clks. |
-- An excellent difussion Time, but the max number of columns its limited by the platform specs. |
-- Even it is an excellent time is not much of gain because this time is the same time of the pipe longitude, thus a result each clock is achieved anyway. |
