Problems solved by technology

However, since designing and using these systems requires developers to learn complex parallel computing theory, and parallel programming is very complicated for most software developers
Thus, it is inappropriate to use traditional methods to solve the problem of using idle computing power of application processors in embedded systems

Embodiment Construction

[0016] figure 1 It is a schematic diagram of the embedded parallel computing system of the present invention. The embedded parallel computing system 1 of the present invention is composed of a host processor 11 , a host bus 12 , a host memory 13 and an application subsystem 14 . When the system is a mobile phone system, the mobile phone host includes a host processor 11, a host bus 12 and a host memory 13, and the host memory 13 is a memory located on the circuit board of the mobile phone.

[0017] Wherein, the host bus 12 is used for communication between the host processor 11 , the host memory 13 and the application subsystem 14 . The host processor 11 can access the host memory 13 and the application subsystem 14 through the host bus 12 . The host memory 13 is used to store the embedded parallel program, which includes the task code of the host task and the subsystem task, and the task code of the host task of the embedded parallel program is the task code of the host tas...

Description

technical field [0001] The invention relates to a computing system and a computing method, in particular to an embedded parallel computing system and an embedded parallel computing method. Background technique [0002] Currently, in the embedded field, especially in mobile phones, software can only use the application processor when it needs to complete specific applications (such as taking pictures). The software reads and writes the registers of the application processor or sends commands to the application processor. After the application processor completes a specific operation, it puts the operation result into the application memory, and then notifies the software to read the operation result. Software cannot use the application processor while doing other computing operations. However, many application processors currently have a more powerful CPU core inside. The above methods do not take full advantage of the computing power inside the application processor. [0...
