Abstract

The invention provides a business function execution method and electronic equipment, and relates to the technical field of terminals. The business function execution method comprises the following steps: firstly, a central processing unit determines algorithm library information required for operating a first business in response to a trigger instruction for the first business; then, according to the algorithm library information, the central processing unit obtains the algorithm library from the external memory and loads the algorithm library to the memory; furthermore, the central processing unit sends address information of the algorithm library in the memory to the target slave processor; and finally, according to the received address information, the target processor calls the algorithm library from the memory and operates the first business. In this way, the algorithm library can be loaded as required in the execution process of the service function, and long-term occupation of the memory space is avoided.

Description

【Technical field】 [0001] The present application relates to the technical field of terminals, and in particular to a service function execution method and electronic equipment. 【Background technique】 [0002] With the development of terminal technology, many terminal devices support central processors and slave processors to cooperate to execute some business functions, thereby increasing the processing speed. For example, for business functions related to digitized signals, digital signal processors such as visual digital signal processors, voice digital signal processors, and video digital signal processors can be used as slave processors in conjunction with the central processing unit. [0003] At present, each algorithm library required by the processor is usually solidified in the firmware. The slave processor completes the processing of corresponding business functions by calling the algorithm library in the firmware. However, solidifying the algorithm library in the...
