Abstract
A versatile SDIO host controller capable of connecting to standardized general interfaces is provided. An SDIO host controller as a one-chip semiconductor integrated circuit device comprising: at least one core of an SDIO host, the core including an SD host engine and an SD host register set and memory that control the SD host engine; a plurality of CPU interfaces that control the SDIO host; and at least one selector that selects among the CPU interfaces. In particular, the SDIO host controller preferably comprises at least an ATA interface and an ATA-SD protocol conversion engine.
Claims7
An SDIO (Secure Digital Input Output) host controller as a one-chip semiconductor integrated circuit device, characterized by comprising:
- two or more cores of an SDIO host, each core including an SD (Secure Digital) host engine and an SD host register set and memory that control the SD host engine independently:
- a plurality of CPU interfaces that control the SDIO host;
- at least an ATA interface and an ATA-SD protocol conversion engine that supports ATA device essential commands, as well as commands for notifying of the status of a power management feature set and status of the SD memory card:
- and two or more selectors that select among the CPU interfaces.
An SD memory card duplication apparatus for duplicating data recorded on an SD memory card, characterized by comprising:
- at least two SDIO host controllers including an ATA interface and an ATA-SD protocol conversion engine that supports ATA device essential commands, as well as commands for notifying of the status of a power management feature set and status of the SD memor card;
- a logic circuit functioning as an IDE host;
- and a selector circuit.
