SUMMARY A software development system and an assembler are essential tools for writing, assembling, testing, and debugging large assembly language programs. A disk-based microcomputer, its operating system, and assembler pro­grams can serve as a development system. All the operations of the computer are managed and directed by the operating system of the computer. The Assem­bler […]

7.4 WRITING PROGRAMS USING A CROSS-ASSEMBLER This section describes a commercially available Z80 cross-assembler and the pro­cess of assembling a program. The description in the following sections is equally applicable to both assemblers and cross-assemblers; therefore, the term assem­bler should be interpreted as the representation of both. The assembly process is illustrated with a simple […]

7.3 ASSEMBLERS The assembler (or the cross-assembler), as defined before, is a program that trans­lates assembly language mnemonics or source code into binary executable code. Here, we are using the term assembler to include all the utility programs (such as Assembler and Linker) necessary for the assembly process. This translation pro­cess requires that the source […]

7.2 OPERATING SYSTEMS The operating system of a computer is a group of programs that manages or over­sees all the operations of the computer. The computer transfers information con­stantly among peripherals such as a floppy disk, printer, keyboard, and video monitor. It also stores user programs under file names on a disk. (A file is […]

7.1 MICROPROCESSOR-BASED SOFTWARE DEVELOPMENT SYSTEMS A software development system is simply a computer that enables the user to write, modify, debug, and test programs. In a microprocessor-based development system, a microcomputer is used to develop software for a particular micropro­cessor. Generally, the microcomputer has a large R/W memory (640K bytes or higher), disk storage, and […]

Software Development Systems and Assemblers A software development system is a computer that enables the user to develop programs (soft­ware) with the assistance of other programs. The development process includes writing, modifying, testing, and debugging of the user programs. In the previous chapter, we dis­cussed how to write a simple assembly lan­guage program and translate […]
