Method and device for loading software modules

Abstract

Disclosed are a method and device for loading a software module. The method comprises: determining a to-be-loaded section in a software module to be a first to-be-loaded section or a second to-be-loaded section according to at least one item of the following information: a use frequency of the to-be-loaded section, power consumption of the to-be-loaded section and a memory size occupied by the to-be-loaded section, the first to-be-loaded section being a to-be-loaded section loaded into a first storage area, and the second to-be-loaded section being a to-be-loaded section to be loaded into a second storage area (S110); and if the to-be-loaded section is the first to-be-loaded section, loading the to-be-loaded section into the first storage area, or if the to-be-loaded section is the second to-be-loaded section, loading the to-be-loaded section into the second storage area (S120). Accordingly, the method and device for loading a software module are capable of improving the comprehensive level of the performance of a chip and reducing the power consumption of the chip.

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 smartphone sensor hubs (Sensor Hub), 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 all Very small, generally around 8KB to 100KB, in order to support more functional applications, the system on chip (System On Chip, SOC) must also be equipped with double-rate synchronous dynamic random access memory (Double Data Rate Synchronous Dynamic Random Access Memory, DDR SDRAM ), DDRSDRAM is also referred to as DDR for short. The power consumption and performance of the software in the chip are ideal when loaded on the SRAM, but the SRAM space of the chip is limited; when loaded on the DDR, the power consumption of the chip will increase,...

[0002] In the field of embedded devices, such as smartphone sensor hubs (Sensor Hub), 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 all Very small, generally around 8KB to 100KB, in order to support more functional applications, the system on chip (System On Chip, SOC) must also be equipped with double-rate synchronous dynamic random access memory (Double Data Rate Synchronous Dynamic Random Access Memory, DDR SDRAM ), DDRSDRAM is also referred to as DDR for short. The power consumption and performance of the software in the chip are ideal when loaded on the SRAM, but the SRAM space of the chip is limited; when loaded on the DDR, the power consumption of the chip will increase, and the performance will also increase It is not as good as the performance performed on SRAM. Therefore, a software loading method is needed to improve the comprehensive level of chip performance and power consumption under the condition of limited chip SRAM memory resources.
