PENTIUM II Pentium II is also a 32-bit processor with 64-bit data bus and 36-bit address bus to address up to 64GB of physical memory space. It is actually a Pentium pro processor with on-chip MMX (Multi Media Extension). It is available with maximum internal ratings of 233 MHz to 450 MHz. The features of Pentium II processor are; Supports the architecture with dynamic execution. Integrated primary (L1) 16-kb instruction and 16-kb write back data cache. Integrated 256kb second level (L2) cache. compatible with previous microprocessors. Supports MMX technology. start and Deep sleep modes provide extremely low power dissipation. Low power GTL + processor system bus interface (GTL: Gunning transceiver Logic). Integrated math co-processor. thermal diode for measuring processor temperature. Pentium II Software Changes The Pentium II microprocessor core is a Pentium Pro. This means that the Pentium II and the Pentium Pro are essentially the same device for software. This section lists the changes to the CPUID instruction; and the SYSENTER, SYSEXIT, FXSAVE, and FXRSTORE instructions (the only modifications to the software). CPUID Instruction
