I remember when GaAs (gallium arsenide) was a hot research topic in the 1980's, but it never got beyond niche markets because CMOS advancing way beyond expectations.
I almost have to laugh that 0.25um GaN is cutting-edge, and 25nm CMOS has been in volume production for more than a year now (flash memory). I say "almost" because 0.25um GaN can run a lot faster than 0.25um Si; I'm curious what kind of speeds will be attainable at smaller geometries.
GaN technology is pretty hot in some academic circles (see presentations at CMOSET conference for example)...that fact that process has been in development since 1999 tells you it is an easy process to work with...Kris
Blog Doing Math in FPGAs Tom Burke 24 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
