calculation program

The computer software system includes: operating system: the core of software system, it is responsible for the computer system in various soft, hard resource management, control and monitoring.

The database management system in a computer system: responsible for all documents,BLN Design information and data management and sharing.

The compiler system: responsible for the user with high-level language prepared by the source program is compiled into machine can understand and executes the machine language.

The network system of the computer system: responsible for cyber source organization and management, make in multiple independent computer room for mutual sharing and communication.

The standard library: according to a standard format prepared by some of the procedures set, these standard procedures including the solution of elementary function, linear equations, ordinary differential equations, numerical integral calculation program.

The service program: also known as utility program. In order to enhance computer system service function and provide a variety of computer procedures, including the user program device, connection,Air mouse editing, debugging, error correction, diagnosis function. In order to enable the computer to be quick and accurate, remember and prison, for decades, to improve the single central processor in the processing speed and accuracy, to improve access speed and capacity made many improvements, such as: increased operations for the basic word length and improve the operation accuracy; the addition of new data types the data, Bluetooth Keyboardor custom, make data with a symbol, used to differentiate instruction and number, and description of the data types in CPU general purpose registers; additionally, the index register, increased indirect addressing function and adding a cache memory and with stack; the memory access technology and virtual memory techniques; the instruction pipeline and the arithmetic pipelining; using multiple functional components and additional coprocessor.

To fully exploit the potential of a single processor, people turned to the development of parallel processing technology.PC remote At the beginning (1952 ) in the ALU designed the parallel arithmetic logic, then using multiple features, namely in the central processor set up independently of each other, and may work at the same time feature. After 30 years of development, with a single processor computer system, performance has reached a very high level, vector supercomputer is the technology crystallization.
