Abstract

The utility model relates to a large capacity memory palm computer. The memory capacity is large, the portability is good, and the operation is convenient. The utility model comprises a palm computer casing and a CPU. A card inserting slot is arranged on the palm computer casing, a CF flash card is arranged in the card inserting slot, and the CF flash card is connected with the CPU through an interface connecting wire.

Description

High capacity internal memory palm PC

The utility model relates to a kind of palm PC, especially relates to a kind of palm PC with high capacity internal memory.

In the background technology, existing P DA (personal digital assistant) and palm PC are various in style, and its function is also varied, except that having basic functions such as recording phone number, work program, the arrangement of personal daily affairs, also have wired or wireless function of surfing the Net.But these products are the less deficiency of ubiquity internal memory all, and the use of a lot of aspects is restricted.Be data and data and the increase internal memory that to preserve user's input better, some palm PC has adopted FLASH MEMORY flash memory technology in the internal memory storage in form, the weak point of its existence is: having adopted the palm PC of FLASH MEMORY flash memory technology is that this module is fixed on the mainboard of palm PC, this information storage to this palm PC is can not produce any influence with reading, to of the same type or adopt wired or wireless mode carries out information and data transmission mutually between two palm PCs, can not produce any influence simultaneously according to certain agreement yet.But, between unrelated two or many palm PCs, just can't carry out the transmission of information and data if get rid of above two kinds of situations.Secondly, this storage capability that is fixed on the flash memory module on the palm PC mainboard neither be very desirable, and what have has only the 2BM internal memory, can't satisfy the demand of client to the palm PC internal memory.In a word, little, the portable difference of memory size is the main weak point that existing palm PC exists.

The purpose of this utility model has been to overcome the weak point in the above-mentioned background technology, and a kind of high capacity internal memory palm PC is provided, and its memory size is big, and is portable good, easy to use.

For achieving the above object, the technical solution that the utility model adopts is as follows:

A kind of high capacity internal memory palm PC comprises palm PC shell and CPU, and its special character is: described palm PC shell is provided with card slot, is inserted with compactflash memory card in the card slot, and compactflash memory card connects with CPU by the interface line.

Above-mentioned card slot can be located at the shell sidepiece.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of mainboard in the utility model;

Fig. 3 is the rear view of Fig. 2;

Fig. 4 is a course of work synoptic diagram of the present utility model.

Number in the figure is described as follows:

1-shell 2-CF flash card, 3-CF flash card card slot, 4-demoder, 5-character library.

Below in conjunction with accompanying drawing the utility model is described in further detail: referring to Fig. 1, Fig. 2, Fig. 3, the utility model comprises shell 1, shell 1 sidepiece is provided with compactflash memory card card slot 3, be inserted with compactflash memory card 2 in the card slot 3, compactflash memory card 2 can freely be pegged graft in compactflash memory card card slot 3, separate with the palm PC fuselage, become detachable.Compactflash memory card 2 comprises plurality of specifications such as 4MB, 8MB, 16MB, 32MB, can select for use as required.Compactflash memory card 2 connects with CPU by the line interface, and system carries out the storage of data information and reads in card.With the special-purpose card slot 3 of compactflash memory card 2 insertion palm PCs, system will discern compactflash memory card 2 automatically and be another memory space except that " main memory ".Compactflash memory card 2 utilization FLASH immediate access technology are not lost data.Referring to Fig. 4, during real work, when palm PC enters open state, the initial detecting before BIOS at first moves the state of the various aspects of the hardware system of inside, i.e. " System self-test ".By the LCDs input information, LCDs is passed to demoder 4 with being about to signal with stylus, and CPU is passed in the instruction that the signal that demoder 4 transmits LCDs " translation " one-tenth system can carry out.After CPU receives instruction, in ROM, assemble program module, be used to support operating system, and according to the instruction that demoder 4 transmits, between RAM and character library 5, store back and forth and read document information, data picture and for information about.Be inserted with compactflash memory card 2 in the compactflash memory card card slot 3 of palm PC, compactflash memory card 2 connects with CPU by the interface line, and according to system directive, CPU stores in flash card or reads information and data.The mode of compactflash memory card preservation or output information and data is that utilization floating boom induction technology is adopted the living voltage difference of cutting down output by CPU, thereby realizes data and information are preserved and exported.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

The utility model adopt internal memory strengthen technology FLASH MEMORY flash memory module with The palm PC fuselage separates, become detachable, can be free at the palm PC that the flash card card slot is housed Between peg graft back and forth, effectively increased the memory size of palm PC, and easy to use, portability Good. The compactflash memory card multi-size is convenient to the consumer and is used;

2. the utility model adopts FLASH flash memory technology, and the protection of relevant data and data need not Battery maintenance;

3. the utility model is low in energy consumption, can support the voltage of 3.3 volts and 5 volts.
