By modeling a circuit board on the human brain, Stanford bioengineers have developed microchips that are 9,000 times faster than a typical PC. Called Neurogrid, these energy-efficient circuits could eventually power autonomous robots and advanced prosthetic limbs.
Bioengineers are smart to take inspiration from the human brain. It's a highly efficient information processor capable of crunching 100 million instructions per second (MIPS). Astoundingly, it only uses about 20 watts to power its 100 billion neurons. Today, our best supercomputers require a million watts to simulate a million neurons in real time (measured in terraflops). A standard desktop computer requires about 40,000 times more power to run and operates about 9,000 times slower.
