Title:
COMPUTATION DEVICE AND ELECTRONIC EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2019/048982
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a computation device and electronic equipment that consume little power. The purpose of the present invention is to provide a computation device and electronic equipment capable of high-speed operation. The purpose of the present invention is to provide a computation device and electronic equipment in which heat generation can be suppressed. The computation device has a first computation unit and a second computation unit. The first computation unit has a first CPU core and a second CPU core. The second computation unit has a first GPU core and a second GPU core. Each CPU core has a power gating function, and has a first data holding circuit connected to a flip flop. The first GPU core has a second data holding circuit capable of holding an analog value and reading out the analog value as two or more bits of digital data. The second GPU core has a third data holding circuit capable of holding a digital value and reading out the digital value as one bit of digital data. The first through third holding circuits each have a capacitor element and a transistor that has an oxide semiconductor.
