Title:
ＰＣＩデバイスに接続される省電力状態に移行可能なデバイスを備える電子機器およびその制御方法
Document Type and Number:
Japanese Patent JP7374588
Kind Code:
B2
Abstract:
An electronic apparatus includes a semiconductor integrated circuit, another semiconductor integrated circuit connected to the semiconductor integrated circuit via a peripheral component interconnect (PCI) bus, and devices (a hard disk drive (HDD), and a dynamic random access memory (DRAM)) connected to the another semiconductor integrated circuit. The semiconductor integrated circuit transmits a predetermined instruction to the another semiconductor integrated circuit, and the another semiconductor integrated circuit shifts the PCI bus to a non-communicable state or a state communicable at low speed. Thereafter, the another semiconductor integrated circuit shifts the devices (the HDD and the DRAM) to a power saving state.
