Unformatted text preview: self, and a leveltwo cache (Known as L2 cache) is external, typically made up of SRAM (static RAM) chips on the motherboard. A static RAM chip requires power to hold its content and has access times in the 10 to 30-nanosecond range. Static RAMs do not require refresh circuitry as do dynamic RAMs, but they take up more space and use more power. Pentium family chips Typical clock speeds Pentium Processor Pentium Processor technology Pentium II Processor 120, 133, 150, 166 and 200 MHz. with MMX 166,200 and 233 MHz. 233, 266, 300, 333, 350, 400, and 450 MHz. Pentium III Processor 450, 500, 750 and 800 MHz. Pentium IV Processor 1 GHz and higher Figure 20.3. Typical clock speeds of microprocessor chips in the Pentium family. The Pentium Processor with MMX technology and the Pentium II Processor chips have 57 new instructions, as well as data types, as compared to the previous Intel microprocessor chips. These instructions and data types are mainly for multimedia enhancements enabling these chips to provide increased performance on a wide variety of multimedia and communications applications. Similarly,, the Pentium III Processor chip has additional new instructions enabling advanced imaging, 3D, streaming audio and video, and speech recognition applications. Thus with a PC based on Pentium III Processor it will be possible to 1. View and manipulate higher resolution and higher-quality images than with previously available PCs, 2. Support high-quality audio, MPEG2 video and simultaneous MPEG2 encoding and decoding, and 3. Have reduced CPU utilization for speech recognition, as well as higher accuracy and faster response time. Virtually all PCs of today give users the flexibility to enhance the functionality of a basic configuration and are said to have an open architecture. For this, the system unit of a PC has expansion slots in which a wide variety of special-function add-on boards (also called add-on cards) can be plugged in. These add-on boards contain the electronic circuitry for a wide variety...
