Digital Microprocessor ICs-Chapter 24

DOI: 10.1016/b978-081551467-1.50025-0


Publisher Summary his chapter discusses digital microprocessor integrated circuits (ICs). Analog electrical signals are still used for many purposes—such as local telephone calls, and for some types of fairly simple computers in automation, etc. However, relatively small but very powerful computers, and also some large supercomputers, now use digital microprocessors for their internal operations. The binary digital programs for these microprocessors consist of extremely long lists of binary (zero or one) numbers. This is called machine language. Groups of these numbers, somewhat summarized into a symbolic format, are called object code, and this is considered to be a sort of language, at a slightly higher level than the raw zeros and ones. The chapter also elaborates on different computer languages.
