thank you !

concerning the "target", it ranges from SRAM-based FPGA to semi-custom,
depending on what tools are available. Of course if we wanted to compete
with Intel, full-custom teams would have to work, but let's be realistic :-)
but whatever step in any direction is apreciated.
I hope it is not too fuzzy :-)
