例如要计算1+2和3+4,数据是1,2,3,4,基本操作是+,从内存输入以上内容到控制单元(CONTROL UNIT),也就是程序计数器,它按输入顺序接收基本操作与数据,并传给算数逻辑单元(ARITHMETIC LOGIC UNIT)做基本运算,将其结果输出到内存中。 STORED PROGRAM COMPUTER 存储程序计算机 sequence ofinstructions storedinside comput...
Logic (from the Ancient Greek: λογική, logike)[1] is the use and study of valid reasoning.[2][3] The study of logic features most prominently in the subjects of philosophy, mathematics, and computer science.Logic was studied in several ancient civilizations, including India,[4] ...
Logic programming is a computer programming paradigm where program statements express facts and rules about problems within a system of formal logic. Rules are written as logical clauses with a head and a body; for instance, "H is true if B1, B2, and B3 are true." Facts are similar to ...
In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU). Some processors contain more than one AU -- for example, one for fixed-point operations and another for floating-point operations. In computer systems, floating-point computations are some...
