Several questions :

1. Approximatly, how many time do we have before the effective sales ? some days ? week ? half a month ? more ?

2. DDR4 memory : if we already have a 8 or 16 Go DDR4 memory, can we use it instead of buying the global package ? If yes, no matter the DDR4 frequency ?

3. Is 1 FPGA enought ? Do we need several FPGA, depending on the algorithm used ?
