Abstract
The invention discloses an embedded software development method. The embedded software development method includes the steps of 1, demand analysis, wherein specific requirements on system development are acquired; 2, preliminary design, wherein a scheme for achieving a target system is sought according to the result generated at the demand analysis stage; 3, detailed design, wherein a response algorithm and an internal data structure are determined for a module in software, and precise description of specific achievement of the target system is acquired; 4, encoding, wherein the scheme designed in the step 3 is described through a computer programming language, and a program executed on a computer is obtained; 5, generating of executive codes; 6, compiling, wherein a source program on a host machine is compiled into object codes; 7, interlinking; 8, debugging, wherein a cross debugger is used for debugging the program, and the debugged program runs on different machines; 9, testing; 10, curing running. Development of embedded software is designed, compiled, debugged, tested and subjected to curing running, so that the expandability of a system is improved, integration of all assemblies is improved, and the development period of the embedded software is shortened.
Description
technical field [0001] The invention belongs to the technical field of software development, in particular to an embedded software development method. Background technique [0002] Embedded system development is a hot spot in the development of computer software today. The key to embedded systems is to combine the system circuitry of a microprocessor or microcontroller with its proprietary software to achieve the highest ratio of system operating efficiency to cost. With the development of computer technology and popularization of applications, embedded systems have penetrated into all aspects of daily life and are widely used in consumer electronics, communications, automobiles, national defense, aerospace, industrial control, instrumentation, and office automation. The number of applications far exceeds that of various general-purpose computers. Embedded system is application-centric, based on computer technology, software and hardware can be cut, and it is a special-pur...
