I think a well chosen hearing aid tube can outperform a classic (not

This application sound like a perfect candidate for a
CPLD.
The Xilinx 9500 series of CPLDs are not low-power, by any
means. They have a formula in the data sheet and a power
calculator program, that are both WRONG! They underestimate
power by a factor of 3!! I reported this to them, and they
said I was right, but they were not going to fix the
documentation! Sheesh!
(The internal architecture is 36-input diode gates with
pull-up resistors. You have two choices of resistor,
low-power and fast.)
The Xilinx CoolRunner II is quite low power, basically a
CMOS FPGA architecture.
