US Patent Issued to SAMSUNG ELECTRONICS on Jan. 13 for "Depthwise-convolution implementation on a neural processing core" (California Inventors)

ALEXANDRIA, Va., Jan. 13 -- United States Patent no. 12,524,656, issued on Jan. 13, was assigned to SAMSUNG ELECTRONICS Co. LTD. (South Korea).

"Depthwise-convolution implementation on a neural processing core" was invented by Jong Hoon Shin (San Jose, Calif.), Ali Shafiee Ardestani (Santa Clara, Calif.) and Joseph H. Hassoun (Los Gatos, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A core of neural processing units is configured to efficiently process a depthwise convolution by maximizing spatial feature-map locality using adder trees. Data paths of activations and weights are inverted, and 2-to-1 multiplexers are every 2/9 multipliers along a row of multipliers. During a depthwise convolution opera...
