Chapter 2 Instructions: Assembly Language
Chapter 2 Instructions: Assembly LanguageReading: The corresponding Chapter in the 2nd edition is Chapter 3, in the 3rd edition itis Chapter 2 and Appendix A and in the 4th edition it is Chapter 2 and Appendix Instructions and Instruction setThe Language to command a computer architecture is comprised ofinstructionsand thevocabulary of that Language is called theinstruction set. The only way computers can rep-resent information is based on high or low electric signals, , transistors (electric switches)being turned on or off. Being limited to those 2 alternatives, we represent information in com-puters usingbits(binary digits), which can have one of two values: 0 or 1. So, instructionswill be stored in and read by computers as sequences of bits. This is called machine make sure we don t need to read and write programs using bits, every instruction will alsohave a natural Language equivalent, called the Assembly Language notation.
after a company that designed the widely spread MIPS (Microprocessor without Interlocked Pipeline Stages) architecture and its corresponding instruction set. MIPS R2000 is a 32-bit based instruction set. So, one instruction is represented by 32 bits. In what follows, we will discuss Arithmetic instructions Data transfer instructions
