Unformatted text preview: ine in the series that could support a Unix operating system. i486: (1989, 1.9 M transistors). Improved performance and integrated the floating-point unit onto the processor chip but did not change the instruction set. Pentium: (1993, 3.1 M transistors). Improved performance, but only added minor extensions to the instruction set. PentiumPro: (1995, 6.5 M transistors). Introduced a radically new processor design, internally known as the P6 microarchitecture. Added a class of “conditional move” instructions to the instruction set. Pentium/MMX: (1997, 4.5 M transistors). Added new class of instructions to the Pentium processor for manipulating vectors of integers. Each datum can be 1, 2, or 4-bytes long. Each vector totals 64 bits. Pentium II: (1997, 7 M transistors). Merged the previously separate PentiumPro and Pentium/MMX lines by implementing the MMX instructions within the P6 microarchitecture. Pentium III: (1999, 8.2 M transistors). Introduced yet another class of instructions for manipulating vectors of integer or floating-point data. Each datum can be 1, 2, or 4 bytes, packe...
