Lecture 9 - MIPS instruction set; binary arithmetic

MIPS architecture, cont'd (text, chapter 3)

Review basic MIPS instructions (text, Figure 4.6, p. 183)

Sharp contract with CISC (complex instruction set) architectures such as the Intel 80x86

Will return to performance issues later in semester

Binary arithmetic

MIPS ALU (text, section 4.5)

An ALU (arithmetic-logical unit) is a combinational circuit capable of computing a variety of arithmetic and logical functions.
