Embodiment Construction
[0032] figure 1 It is a block diagram of a system for implementing device sharing according to an embodiment of the present invention. In this embodiment, the system for implementing device sharing shares one or more hardware and / or software devices (eg, device 104 ) connected to the first processor between the first processor 100 and the second processor 110 . Hardware devices may include touch screen, GPS, Bluetooth, radio and / or other peripheral devices connected to computer 210 or ARM microcontroller 200 . The software device may include game software, player software and / or other application software configured on the computer 210 or the ARM microcontroller 200 . The first processor 100 is connected to the second processor 110 through a high-speed bus, and the high-speed bus (for example, a USB bus) is used to transmit various communication protocols (for example, UART, USB) between the first processor 100 and the second processor 110. I2C, GPIO and / or other communicati...

The invention discloses a system and a method for realizing device sharing, and is used for realizing the action of sharing one or more devices between a first processor and a second processor, wherein the first processor is connected with the one or more devices, and the second processor is connected with the first processor by a high-speed bus; the data communications between the first processor and second processor are respectively based on data communication protocols respectively supported by the one or more devices; when the sharing is required, the second processor sends a sharing request to the first processor, then the first processor sends the information of devices corresponding to the sharing request to the second processor, and the second processor respectively carries out operations on corresponding virtual devices according to the received device information, and the operating datathe is sented to the first processor, finally, the first processor carries out corresponding operations on corresponding hardware and / or software devices according to the received operating data, and returns the operation results to the second processor. The invention effectively releases computer interfaces and improves the utilization ratio of device.
Description
technical field [0001] The invention relates to the field of equipment management of computer systems, in particular to a system and method for realizing equipment sharing. Background technique [0002] With the rapid development of computer technology, there are more and more computer peripheral devices with various functions. Many external devices do not support USB communication protocols, but support communication protocols such as UART, I2C, and GPIO. When these devices are connected to a computer, multiple data interfaces are required, which increases the complexity and instability of the computer system. Moreover, the hardware resources of the personal computer are limited, and there are not enough interfaces to connect many such devices. Due to the limitation of the number of interfaces, the expansion of the functions of the personal computer is seriously affected. [0003] In addition, for multiple operating systems, devices connected to each other are usually dr...
