Possible erratum with the statement that "50% more power is provided for unconfigured or suspended devices (150mA up from 100mA)."

Table 7.7 of the USB 2.0 specification states that low-power devices are limited to 0.5mA and high-power devices are limited to 2.5mA during suspend.
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 ...
