Description
Technical field
This paper relates to the TF card that a kind of expansion has coprocessor, particularly realizes the method and system of SDIO expansion through standard SD memory interface.
Background technology
SDIO has defined a kind of Peripheral Interface on the SD standard.At present, SDIO has two types of main application---and removable and not removable.Present movable equipment is used for increasing bluetooth, camera, GPS and 802.11b function as the expansion equipment of Palm and Windows Mobile.Movable equipment is not followed identical electrical standard, but does not require and meet physical criterion.Comprise 802.11 chips that connect CPU through SDIO in some mobile phone.This measure is used for prior function with the I/O pin resource of " preciousness ".
Bluetooth, camera, GPS and 802.11b equipment have the using standard that aims at their definition.These using standards are very alike with the class standard that is the definition of PCI and USB device.They allow any host equipment and any peripheral hardware " conversation ", as long as they all support using standard.
An important difference between SDIO and SD calliper model is to have increased the low speed standard.The SDIO card only needs SPI and 1 SD transmission mode.The intended application of low speed card is to support low speed I/O ability with the hardware spending of minimum.The low speed card is supported application such as similar modulator-demodular unit, bar-code scanner and GPS receptacle.(storer+SDIO), full speed and 4 bit manipulations all are mandatory requirements to card internal storage and SDIO part as far as " combination " card.
To be used in the specification of expansion card with the draw-in groove of the same terminal shape of SD memory card.Call the SDIO card to corresponding SDIO draw-in groove (socket), the expansion card is called the SDIO card.
Be the specification of using the SD card in order in PC and PDA etc., to add function,,, much more more be used among the small and exquisite PDA to than in notebook computer owing to can use card and the slot also littler than PC card shape.Main product sold has, towards PHS address card and the bluetooth communication card of PDA, wireless network card, small digital cameras etc.
In order to use SDIO, corresponding slot must be arranged, the not corresponding SDIO card of the dedicated slot of memory card such as digital camera.Can insert SD memory card in the SDIO slot reads and writes.
All SD and SDIO card all must be supported older SPI/MMC pattern.This pattern support four line serial interfaces (chip is selected for clock, sequence input, sequence output) at a slow speed are compatible with sequence terminal interface (SPI) and many microcontrollers.
The purposes of using the video camera lens SD socket at SDIO interface is to insert storage card incessantly.Support the PDA of SDIO interface, notebook computer etc. can connect and resemble gps receiver, Wi-Fi or Bluetooth adapter; Modulator-demodular unit, LAN adapter, barcode readers; The FM radio; Television receiver, radio frequency authentication reader, perhaps digital camera or the like adopts the equipment of SD standard interface.
