Embodiment approach 1
[0102] figure 1 It is a block diagram of the installation apparatus concerning Embodiment 1. The installation device according to this embodiment has a function of controlling MMC and SD cards which are examples of removable cards, and embedded modules corresponding to the bus standards of these cards. The installation device according to the present invention is, for example, a mobile phone terminal. The same applies to the following embodiments.
[0103] Such as figure 1 As shown, the installation device 100 includes a host computer 10, a card host LSI 101, card buses 103, 104, and card slots S105a, S105b. The card host LSI101 has the ability to control multiple ( figure 1 2 in ) Removable card or function as a card module embedded in the module. figure 1 Among them, detachable SD cards 105a and 105b corresponding to 4 digits are inserted into the card slots S105a and S10b.
[0104] The card host LSI 101 includes a host I / F 11 for receiving external control signals...
Embodiment approach 2
[0155] In Embodiment 2, an installation device including a card host LSI including a plurality of two card host I / Fs, two card bus terminals, and a bridge circuit described in Embodiment 1 will be described. combination.
[0156] Figure 8 It is a block diagram of the installation apparatus concerning Embodiment 2. exist Figure 8 in, for with figure 1 common structural elements attached to the figure 1 same symbol. Such as Figure 8 As shown, the installation device 200 includes: a host computer 10, a card host LSI 201, card buses 103, 104, 213, 214, 215, 216, and 217, and card slots S205a, S205b, S205c, S205d, S205e, S205f, and S205g. exist Figure 8 Among them, the card slots S205a, S205c, S205e are respectively inserted into the MMCs 105c, 105d, 105e corresponding to 8 digits, and the removable SD card 105f is inserted into the card slot S205g.
[0157] The card host LSI 201 has: card host I / F202a (#A), 202b (#B), bridge circuit 206a (#AB), card host I / F202c (#C)...
Embodiment approach 3
[0167] Figure 10 It is a block diagram of the installation apparatus concerning Embodiment 3. exist Figure 10 in, for with figure 1 common structural elements attached to the figure 1 The same symbols are used, and detailed explanations thereof are omitted here.
[0168] Such as Figure 10 As shown, the installation device 300 includes: a host computer 10, a card host LSI 301, card buses 103, 104, an embedded MMC 305c corresponding to 8 bits, and a card slot S105b. That is, the card host LSI 301 controls the embedded MMC 305 c via the card bus 103 . In addition, in the card host LSI 301, the host I / F 31 has a high-speed boot sequencer (sequencer), and has a boot (BOOT) switching terminal 310, which is the same as the figure 1 The card host LSI101 is different. The high-speed startup sequence controller 14 starts up when the power supply of the card host LSI 301 is turned on when the lead-in switching terminal 310 is enabled.
[0169] In addition, the boot program BT...
