| 摘要 |
The proposed invention discloses a card reader controlling apparatus based on Secure Digital (SD) protocol, which comprises a high-speed bus interface, at least one SD host, at least one SD connection interface and SDIO connection interface (SD/SDIO interface), at least one bridge, and at least one other specific memory card connecting interface. The card reader controlling apparatus according to the proposed invention is capable of directly accessing data from/to an input/output device compatible with the SDIO connection interface (e.g. an SD card) or one other specific memory card via the high-speed bus interface. Thus, multiple format conversions performed by other peripheral bus interfaces (such as an USB interface) as the prior art can be by-passed or eliminated.
