Transportable Tualatin

In the street crisis of high technologies. One of the largest industries, that, which else recently all surprising with prompt development and solid dividends, has suddenly risen. The prices for the high technology products fall. It pleases potential buyers, but afflicts manufacturers as there is no money for advanced design.

In these conditions all save, reducing employees and freezing perspective projects. Thus, one wait for the crisis termination, others work and try to find a way out of the formed position, strengthening the market and the corporation. We will give to them due - they work for us though we not always understand it and we appreciate, often doing early and biassed outputs.

Recently it is accepted to abuse computer corporations often. For drivers, BIOS and design of motherboards, for the high prices, for advertising, etc . Sometimes deservedly, sometimes is not present. AMD corporation for high energopotreblenie and considerable teploobrazovanie processors, Intel for support of Rambus units with its high price, for Pentium 4 with its high frequency, etc .

However processors AMD are popular, price RIMM falls, high efficiency of two-channel solution in i850 recognises everything, and Pentium 4 continues to win the world. Step-by-step time places all on the places.

Today contrary to Intel crisis declares the new processor created on the basis of new kernel Tualatin, the new procedure which has appeared thanks to implantation.

To nobody a secret, that the traditional architecture of processors grounded on usage of 0,18 microns tehprotsessa, practically, has reached the limit. For Pentium III with kernel Coppermine it is somewhere around 1,2-1,5 GHz that leads to a low dice yield for the upper models of processors.

Output from the formed position — or radically to change the kernel architecture, or to perfect a procedure, reducing the sizes of units on a chip. Experts of Intel have gone both paths. For example, for Pentium 4 NetBurst architecture has been created. The refinement of process of production has allowed to create kernel Tualatin on the basis of previous development Coppermine.

The new procedure 0,13 microns provides essential reduction of the sizes of chips of processors that allows at increase in operating frequencies, to lower a kernel supply voltage (to 1,4 In and more low), it energopotreblenie and, accordingly, the heat release, Besides, reduction of the sizes of chips increases their output from one silicon slice that reduces the cost price and the price of finite products.

But implementators and production workers have gone further away. They not only have improved a procedure, but also have passed from silicon slices in the size of 200 mm, to slices of 300 mm. It has allowed at usage tehprotsessa 0,13 microns to quadruple an output quantity of chips in comparison with previous tehprotsessom 0,18 microns and slices of 200 mm.

In addition to it, copper interconnectings and insulators with a small dielectric coefficient that allows to reach rises of operating frequencies have been used.

All it has allowed to adjust release of processors with a kernel named Tualatin. The first models of processors with this kernel which has the cache memory of second level L2 in size of 512 Kbytes, integrated into a chip, are oriented to transportable solutions. These processors have received the name of Pentium III-M (Mobile Pentium III-M).

Key parametres Mobile Pentium III-M

The improved processing technique of Intel SpeedStep:

• Switching between modes of maximum productivity and economical consumption of energy depends on needs of the user,
• Does not demand user intervention,
• Possibility of compulsory switching in a mode of maximum productivity.

State Deeper Sleep:

• The new mode of dynamic power management provides increase in uptime from the secondary generator,
• The processor supply voltage decreases to the value less "the minimum worker", thus its inwardness is saved.

Support of processors Mobile of Pentium III-M is carried out by new specialised sets of system logic (chip sets) of a series i830 with habovoj the architecture, created specially for transportable solutions. First such chip set of the given series became i830MP.

Key parametres i830MP: support of memory SDRAM PC 133, the optimised controller of memory (hidden delays at calls to memory are reduced to 25 %), support to 1 Gbyte of memory SDRAM, 6 built in ports USB, the integrated network adapter, support of modes lowered energopotreblenija (the improved processing technique of Intel SpeedStep, state Deeper Sleep and permanently delete. ).

The chip set i830MP carries out support of the external accelerator (AGP 4X or AGP 2X). However in the near future chip set release i830M, supporting the integrated drawing or external AGP videoadapter, and also i830MG with the inexpensive built in graphics adapter is planned.

Productivity of new processors Mobile of Pentium III-M in patterns with i830M is shown by the results of tests resulted on fig. 1-4.
