Software module loading method and apparatus

Abstract

The present invention discloses a software module loading method and apparatus. The method comprises: determining a to-be-loaded section of a software module as a first to-be-loaded section or a second to-be-loaded section according to at least one item of the following information: use frequency of the to-be-loaded section, and power consumption of the to-be-loaded section and a memory size occupied by the to-be-loaded section, wherein the first to-be-loaded section is a to-be-loaded section loaded to a first storage area, and the second to-be-loaded section is a to-be-loaded section loaded to a second storage area; and if the to-be-loaded section is the first to-be-loaded section, loading the to-be-loaded section to the first storage area, or if the to-be-loaded section is the second to-be-loaded section, loading the to-be-loaded section to the second storage area. Therefore, according to the software module loading method and apparatus provided by the embodiments of the present invention, performance of a chip and a comprehensive level of power consumption can be improved.

Description

technical field [0001] The present invention relates to the field of information technology, and more specifically, to a method and device for loading software modules. Background technique [0002] In the field of embedded devices, such as smart phone sensor hubs (SensorHub), wearable devices and other devices with limited memory resources, in order to reduce device costs, the memory space of Static Random Access Memory (SRAM) is very small. Generally, it is around 8KB to 100KB. In order to support more functional applications, the System On Chip (SOC) must also be configured with Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM). DDR SDRAM is also referred to as DDR. The software in the chip The power consumption and performance when loaded to SRAM are ideal, but the SRAM space of the chip is limited; when loaded to DDR, the power consumption of the chip will increase, and the performance is not as good as that executed on SRAM. The software loading me...
