A decade ago, an idea was born in a laboratory at the University of California at Berkeley to create a lingua franca for computer chips, a set of instructions that would be used by all chipmakers and owned by none.
It wasn’t supposed to be an impressive new technology, it was merely supposed to get the industry on the same page, to simplify chip-making in order to move things forward.
But a funny thing has happened on the way to a global chip standard: RISC-V, as the Berkeley effort is known, has begun to produce some technical breakthroughs in chip design.
As just one example, a recent microprocessor design using RISC-V has a clock speed of 5 gigahertz, well above a recent, top-of-the-line Intel Xeon server chip, E7, running at 3.2 gigahertz. Yet the novel RISC-V chip burns just 1 watt of power at 1.1 volts, less than one percent of the power burned by the Intel Xeon.
