Most of the computers used on rockets and missiles are "special-purpose computers." A special computer refers to a computer specially designed to solve a specific problem, for a specific application field or for a certain algorithm; such as a steel rolling control computer that controls the steel rolling process, a special computer that calculates missile trajectories, etc., that solves specific problems. It has fast speed, high reliability, simple structure and low price.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
General-purpose computers can solve many types of problems and are highly versatile, such as PCs; special-purpose computers are equipped with software and hardware to solve specific problems, but can solve specific problems at high speed and reliably, such as Most of the computers used on missiles and rockets are special purpose computers.
A special-purpose computer refers to an electronic computer designed and manufactured specifically to solve a specific problem. It is a computer specially designed for a specific application field or for a certain algorithm. Its characteristic is that the system structure and special software are efficient for the designated application fields, but are inefficient or even ineffective for other fields.
Special-purpose computers generally have fixed stored programs.
For example, the steel rolling control computer that controls the steel rolling process, the special computer that calculates missile trajectories, etc., can solve specific problems quickly, with high reliability, simple structure, and low price.
Characteristics of special-purpose computers
A computer with a single function that is designed and manufactured for a specific purpose
Narrow scope of application
Simple structure
Cheap price
High work efficiency
The difference between general-purpose computers and special-purpose computers
A special-purpose computer is a computer specially designed for a specific application field or for a certain algorithm. Its characteristic is that the system structure and special software are efficient for the designated application fields, but are inefficient or even ineffective for other fields.
The difference between special-purpose computers and general-purpose computers is that running programs generally do not need to be loaded from peripherals into memory. Instead, the programs to be executed are placed in memory in advance, and the computer starts When running, the program inside the memory will be executed according to certain rules. It rarely requires special system program control. Even if there is control, it will be much simpler than the system program of a general-purpose computer.
Special-purpose computer programs cannot be replaced, and user-written programs are not accepted, such as mobile phones, car computers, etc.
Special-purpose computers rely on a wide variety of types to meet the needs of different aspects. From a single computer, the function is relatively single. However, overall, the convergence of special-purpose computers applied to different aspects can also achieve general purpose Effect.
