The advantage is that the FPGA can be reprogrammed - like an SRAM-based FPGA. However, unlike an SRAM-based FPGA, it is not sensitive to radiation, and thus is ideal for space-based applications. Currently antifuse-based FPGAs provide radiation resistance, but are only one-time programmable. So carbon-based FPGAs combine the advantages of SRAM-based and antifuse-based FPGAs.
As we now know NuPGA is no longer pursuing FPGA technology but rather fully committed to farther develop its monolithic 3D IC technology breakthrough. Accordingly it change its name to MonolithIC 3D Inc. More information could be found on its web www.MonolithIC3D.com
How is this advantageous over regular FPGA? I am currently doing research on speeding up the routing process for regular FPGA for dynamic runtime reconfiguration. So I would be interested to know how much reconfiguration speed-up that this can give.
Blog Doing Math in FPGAs Tom Burke 15 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 ...
