I designed a hardware-software system to create thermal ex-core neutron energy spectrum signatures in operating pressurized water nuclear plants. We used 32 bit integers as far as we could, even though the ADCs were only 12 bit, because speed was of the essence, and there was a lot of math going down. We used 32 v. 16 bit integers because the math took results into that range. I have not kept up with speeds in hardware, but imagine that the IEEE 754 in hardware must be pretty fast. ~R~ 72/73 de Rich NE1EE The Dusty Key On the banks of the Piscataqua ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
