Abstract
The present invention relates to a multiplex CPU storing card sharing device, its characterized in that it comprises: multiplex CPU, storing card relay, CPU status indicating part, storing card, the said storing card relay respectively interconnects with each CPU of the multiplex CPU and storing card, the said CPU status indicating part respectively interconnect with each CPU of the multiplex CPU. When it connects with a storing card without especial protocol and entirely quotes each CPU with electricity configuration, through affirmation the connecting state of CPUs, to make each CPU separately connect with one storing card, thus can decrease the consumption of electric power, and enhance processing velocity. And it can save factory expense because it need not use special control CPU.
Description
Technical field
The present invention relates to sharing of a kind of storage card, being specifically related to a kind of is the storage card sharing device of the multiple CPU of feature with following content.It is characterized in that: in order to handle various functions, be suitable for when possessing the CPU of other performance more than 2, need not special agreement and also can connect storage card easily by a plurality of CPU at multi-functional compound portable machine and calculation element.
Background technology
Usually central processing unit (CPU:central processing unit) is to possess control to explain and the computer system part of exectorial circuit, forms computer hardware jointly with memory storage, I/O device.For computing machine, central processing unit is equivalent to human brain, and the accounting and the logical operation of data are carried out in its control and the whole computer systems of management.The execution said procedure is that the central processing unit internal hardware factor of purpose comprises ALU (ALU), control device (control unit), register and memory storage interface etc.The CPU of mainframe computer forms with large-scale cabinet and circuit substrate substantially, and small-size computer is to carry out cpu function by a microprocessor chip of being made up of VLSI.Recently, multi-function peripheral device etc. is using a plurality of central processing units.
Fig. 1 is the structural drawing that connects storage card when traditional multi-purpose machine or computing machine use a plurality of CPU.It by a plurality of CPU10 with for a plurality of CPU10 and storage card are formed by the special storage card control CPU20 that the interface is connected.
When a plurality of CPU10 connect storage card 30, receive and dispatch control command and data etc., adopted special storage card control CPU20 in order to wait by agreement between storage card control CPU20 coupling CPU10 and the storage card 30 and electricity configuration.
When using the multifunctional portable device of traditional a plurality of CPU or computing machine etc., its drawback is: connect a storage card 30 in order to make several CPU10, must control CPU20 at storage card agreement between CPU10 and the storage card 30 is set, the configuration of coupling electricity, very loaded down with trivial details.And, continue to use 2 above CPU such as CPU10, control function CPU20, thereby increase electric power consumption in order to connect a storage card 30.In addition, the another kind of drawback of classic method is: the CPU10 on the platform connects storage card 30 indirectly by special storage card control CPU20, handles the path thereby increase, and slows down the processing speed of data and control signal etc.
Summary of the invention
The present invention invents for the drawback that solves above-mentioned conventional art, the purpose of its invention is to share method for the storage card that a kind of multiple CPU is provided, it is characterized in that: when the multi-purpose machine that uses a plurality of CPU connects a storage card, need not special agreement, in the time of the electricity configuration of quoting each CPU fully and being had, by confirming storage card connection status between the CPU, make storage card of each CPU separate connection, thereby reduce power consumption.
In order to realize above-mentioned purpose of the present invention, the invention provides a kind of is the storage card sharing device of the multiple CPU of feature with following content, and it comprises: a plurality of CPU that carry out mutual difference in functionality; When connecting, CPU receives order, the storage card of storage data; Among a plurality of CPU one when connecting said memory card, described a plurality of CPU are connected to a shared storage card repeater by the mode of interconnection respectively; Understand above-mentioned CPU and whether be in the CPU state instruction unit of connection status.And CPU state instruction unit is controlled the interruption that other CPU connects storage card, till the CPU that is in connection status finishes operation when making CPU among a plurality of CPU connect storage card.The input of described storage card repeater, output port successively respectively with a plurality of CPU in each CPU and storage card interconnection, described CPU state instruction unit respectively with above-mentioned a plurality of CPU in each CPU interconnection.
As mentioned above, the present invention is that a plurality of CPU need not special control CPU, shares a storage card and directly connection, thereby more reduces power consumption than classic method, improves processing speed.And significantly do not reduce manufacturing expense because not using special control CPU.

Embodiment
As follows, present invention will be described in detail with reference to the accompanying embodiment.
Fig. 2 is a device synoptic diagram of sharing the storage card of multiple CPU among the present invention.
Even being a plurality of CPU, the present invention do not exist to connect the agreement that special storage card is a purpose, in the time of the electricity configuration of quoting each CPU fully and being had, by the connection status of storage card between the affirmation CPU, but make storage card of each CPU separate connection, thereby can reduce power consumption.
In addition, as shown in Figure 1,, when a plurality of CPU10 connect storage card 30 indirectly by a control CPU20 on the platform, increase and handle the path, slow down processing speed according to classic method.But the present invention be each CPU not via special control CPU Direct Attached Storage card, improve processing speed.
Fig. 2 is a plurality of CPU101-103 of prompting, confirm whether CPU101 connects the CPU state instruction unit 86 of storage card 30 and set and join, so that CPU101-103 connects the storage card repeater 88 of storage card 30.
When CPU 101 execution were stored in the data supervisor of storage card 30 by 88 controls of storage card repeater, whether CPU state instruction unit 86 perception CPU101 connected storage card 30.
And a plurality of CPU101-103 are in order to be connected to storage card 30, at first to be connected to CPU state instruction unit 86, understand other CPU and whether connect storage card 30, connect storage card 30 when being in not user mode.
CPU101 is connected to storage card 30 by storage card repeater 88, and in the process of service data control etc., and when other CPU102-103 will connect storage card 30,86 transmission of CPU state instruction unit connect can not signal, and prompting can't connect storage card 30.After CPU101 finishes storage card 30 connections, when connecting storage card 30 by CPU102-103 again, send connection possibility signals, through storage card repeater 88 connection storage cards 30 by CPU state instruction unit 86.
As mentioned above, according to the present invention, when the multi-purpose machine that uses a plurality of CPU connects a storage card, need not special agreement, in the time of the electricity configuration of quoting each CPU fully and being had, confirm the storage card connection status of CPU101-103, thereby can make storage card of each CPU separate connection.
