Abstract

The invention provides a method for dynamic hardware and software partitioning by considering the hardware pre-configuration factors. The method is characterized in that the dynamic hardware and software partitioning is carried out during the program running process, then one or more functions are configured on the reconfigurable hardware resource, a function list (f1,..., and fm) to be classified is kept for the function to be partitioned, wherein fk is defined to be speedup ratio of hardware, and k is defined to be a function to be partitioned; and k is equal to 1,..., and m, wherein m represents the number of the functions to be partitioned, the functions are configured based on the hardware acceleration ratio, and the hardware pre-configured factors are considered. The method can conduct the dynamic hardware and software configuration to the functions based on the hardware acceleration ratio and fully utilize the hardware resources of the system, thereby remarkably improving the task processing efficiency of the entire system.

Description

technical field

[0001] The invention belongs to the technical field of computer software, and relates to a dynamic software and hardware division method considering hardware preconfiguration factors. Background technique

[0002] According to the division level and granularity, the research on dynamic software and hardware division is mainly divided into two ideas.

[0003] The first idea was proposed by George et al. at the Design Automation Conference in 2003, and continued to develop in their later work. It mainly uses a special cache memory to record the frequency of loop execution in a software program, and selects the loop with the highest execution frequency. , extract the data flow graph after disassembling its machine code, and run an online synthesis program on an additional microprocessor to synthesize the data flow graph into a logic circuit and configure it on a programmable device. In this way, designers do not need to consider the division of software and har...
