[0057] see figure 1 , which is the flow chart of the first embodiment of the control method of the configurable peripheral device of the present application:

[0058] Step 101: When the first subsystem obtains the control right of the configurable peripheral device for the first time, it initializes the configurable peripheral device and generates first configuration information.

[0059] When the first subsystem initializes the configurable peripheral device, it can allocate resources including address space for the configurable peripheral device, and the resources can also include interrupt resources, etc., and write the above resources into the configuration space of the configurable peripheral device In the configuration space, the configuration space is usually composed of multiple registers, which are used to store various resources, and then provide service programs for the configurable peripheral devices, and finally set the address space allocated to the configurable ...

[0092] see Figure 4 , which is the block diagram of the first embodiment of the portable terminal of the present application:

[0093]The portable terminal includes: at least two subsystems, the at least two subsystems include a first subsystem 410 and a second subsystem 420, and at least one configurable peripheral device 430, the at least one configurable peripheral device 430 is the at least one Shared equipment for both subsystems. Among them, for the convenience of example, Figure 4 Only the above two subsystems and one configurable peripheral are shown in .

[0094] Wherein, the first subsystem 410 includes:

Abstract

The embodiment of the invention discloses a control method and a portable terminal for a configurable peripheral device. The portable terminal comprises at least two subsystems and at least one configurable peripheral device, when obtaining a right of controlling the configurable peripheral device at first time, a first subsystem of the two subsystems initializes the configurable peripheral device and uses the configurable peripheral device according to distributive first configuration information. The method comprises the following steps of backing up the first configuration information, restoring configuration of the configurable peripheral device according to the first configuration information when the right of controlling the configurable peripheral device is switched from a second subsystem to the first subsystem so as to enable the first subsystem to use the configurable peripheral device. The control method and the portable terminal for the configurable peripheral device just need to implement initialization when the subsystem obtains the right of control at first time, configuration information backed up in the process of initialization is used for configuration of the configurable peripheral device in the following time, therefore control time delay of a system is shortened, and occupation of system resources is reduced.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a control method of configurable peripheral equipment and a portable terminal. Background technique [0002] The portable terminal with hybrid system architecture is based on the existing PC with only one system, and embedded with at least one other system PC. Different systems can work together and play their respective advantages. The existing common portable terminal with mixed system architecture usually integrates a main system (for example, X86 system, adopting windows operating system) and a slave system (for example, ARM system, adopting android operating system), between the master system and the slave system Shared devices, such as display screens, keyboards, mice, wireless modules, etc., can be shared. [0003] The inventor found in the process of researching the prior art that in the existing hybrid system terminals, configurable peripherals, suc...
