The US Patent and Trademark Office has issued patent number 9,423,866 for an asynchronous processor that automatically adjusts the operating voltage to operate the processor at its point of highest energy efficiency.
Combined with patents 10,205,453 and 10,128,747 the solution includes the innovations required for power management and frequency-controlled voltage sources. Together, this technology improves microcontroller energy efficiency by up to a factor of ten, Eta Compute claims.
"We have a growing intellectual property (IP) portfolio based on the disruptive technologies being developed at Eta Compute that consumes only a fraction of the power of existing solutions and redefines the standard for ultra-low power embedded solutions," said Gopal Raghavan, co-founder and CEO of Eta Compute, in a statement. "This newest patent complements our existing patented technology, which is the foundation of a diverse and wide-ranging set of applications that deliver machine intelligence to the network edge."
