Multiple CPU storage card sharing device

Abstract

The present invention relates to a memory card sharing device of multiple CPUs, which is characterized in that it comprises: multiple CPUs, a memory card repeater, a CPU status indicating unit, and a memory card, and the memory card repeater is connected with the multiple CPUs respectively. The CPUs and the memory cards are interconnected, and the CPU status indication unit is respectively interconnected with each CPU in the multiple CPUs. When connecting a memory card, it does not need a special protocol and fully utilizes the electrical configuration of each CPU. At the same time, by confirming the connection status of the memory card between CPUs, each CPU can independently connect a memory card, thereby reducing power consumption. Improve processing speed. And because no special control CPU is used, manufacturing costs are saved.

Description

technical field [0001] The present invention relates to a sharing of memory cards, in particular to a memory card sharing device for multiple CPUs characterized by the following content. It is characterized in that: in order to process various functions in the multifunctional composite portable machine and computing device, when two or more CPUs with other functions are used, memory cards can be easily connected by multiple CPUs without special protocol. Background technique [0002] Usually, the central processing unit (CPU: central processing unit) is a part of the computer system with a circuit that controls interpretation and execution of commands, and together with memory devices and input and output devices, it forms computer hardware. For a computer, the central processing unit is equivalent to the human brain. It controls and manages all computer systems, and performs data calculation and logical operations. The internal hardware elements of the central processing u...

Problems solved by technology

[0005] When using traditional multi-functional portable devices or computers with multiple CPUs, the disadvantages are: in order to connect several CPUs 10 to one memory card 30, it is necessary to set the protocol between the CPU 10 and the memory card 30 in the memory card control CPU 20 to match the power supply. configuration, very cumbersome

Moreover, in order to connect one memory card 30, two or more CPUs, such as the CPU 10 and the control function CPU 20, are continuously used, thereby increasing power consumption.

In addition, another disadvantage of the traditional method is that the CPU 10 on the platform controls the CPU 20 to indirectly connect to the memory card 30 through a special memory card, thereby increasing the processing path and slowing down the processing speed of data and control signals, etc.
