Method for constructing synergic function library of software and hardware

Abstract

The invention provides a method for constructing a synergic function library of software and hardware, which is characterized by comprising the following steps: firstly, an external interface is stated for the synergic functions of the software and the hardware; the same function is realized by the synergic functions of the software and the hardware in different modes; software functions are realized in a software coding mode, and the hardware functions are realized by comprising hardware interface codes and hardware configuration files realized by the functions; the software functions and the hardware interface codes are packaged together and form the synergic functions of the software and the hardware together with the configuration files of the realization mode of the hardware, and an abstract synergic function library of the software and the hardware is formed by a plurality of synergic functions of the software and the hardware; and the formed function library can be invoked in other programs. The system function library of the software and the hardware, which is constructed by adopting the method, is convenient for software personnel to ignore the difference of the functionsof the software and the hardware and enhance the programming efficiency when the software personnel develop an embedded type system.

Description

technical field [0001] The invention belongs to the technical field of computer software, and relates to a method for constructing a software-hardware collaborative function library. 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 hardware, and can di...

Problems solved by technology

[0012] Although specialized hardware supporting reconfigurable computing operating systems has been proposed in some studies, it is mainly responsible for configuration information and reconfigurable resource management, and process scheduling and switching are still done by software.

[0013] In addition, the current research on process (line) level dynamic software and hardware partitioning does not pay enough attention to the transparent programming model of software and hardware. The software and hardware (line) processes are visible to designers, and programmers create a software or hardware At the same time, it actually implies the division of software and hardware for corresponding functions. Although it is possible to add special codes and circuits to migrate software and hardware into (threads), it is necessary to modify the operating system and underlying hardware to provide support. an ideal solution
