Transportable solutions of Intel
(Continuation)

· switching between modes of maximum productivity and economical consumption of energy depends on needs of the user;

· there is no necessity of user intervention;

· there is a possibility of compulsory switching in a mode of maximum productivity.

· 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.

It is necessary to mark, that active implantation of systems on the basis of processors Mobile of Pentium III-M is linked to heightened interest of the corporation of Intel to sector of transportable solutions. It speaks predicted steady durable growth of the given market segment: IDC and Dataquest estimate rates of annual growth in 15 % up to 2005

However implantation of new solutions has demanded not only developments of the new architecture of processors and their implementation, but also solution of variety of problems. Not the last place among these problems is occupied with such questions, as development nizkoprofilnyh tanks of the processors, appropriate guidelines on maintenance of optimal thermal modes, and also automatic and automanual monitoring of operation of hardware and, of course, release of a new generation of units of support.

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. On a plan of the implementators, new sets should replace on this post a popular chip set i440МX — the improved, transportable variant i440BX. By the way, the specialised set of system logic i440BX (i440BX AGPset), released in a variant for desktop computers, workstations and servers, thanks to high efficiency, wide functionality and remarkable operation properties became the most mass for all history of similar units.

However, despite former efficiency and popularity for designers, the architecture of bridges step-by-step loses the adherents as in the course of perfection of a construction of computers and their accessories in the increasing degree its limitations began to appear. First of all the architecture of bridges possesses following lacks:
· the limited capacity;
· absence of the registration of a data type;
· a divided subsystem of input-output.

On change of the become obsolete structure constructed on the basis of North Bridge and South Bridge, the architecture which has found the incarnation in more modern chip sets has come habovaja.

Habovaja the architecture possesses following features:
· the doubled capacity at the expense of usage of two competitive streams;
· allocation of streams;
· usage of the selected streams;
· component integration.

All it provides following advantages:
· the best in the class productivity at level of all system;
· optimisation for stream applications and the multitask environment;
· high performance by operation in networks and parallelism.

The first specialised set of system logic oriented to systems with Mobile Pentium III-M (on a basis habovoj architectures), the chip set i830MP, entering into i830 set bar became constructed.

Key parametres i830MP are that: support of memory SDRAM PC133, 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 (Intel SpeedStep, 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.

The set of chip sets i830

The purpose of development of the new chip sets, intended to replace sets of the previous generation, was not only tendency to provide the big productivity of transportable systems. The matter is that the high-powered processors constructed on the basis of the architecture of kernel Tualatin, demand specific features of maintenance. To meet these requirements are called not only the special converters of the power supply appropriate to the specification V M 8.5 and allocated on motherboards, but also the appropriate sets of system logic specially oriented to transportable solutions. These chip sets provide the co-ordinated and effective operation of processor Mobile of Pentium III-M and other parts of the transportable computer.

Productivity of new processors Mobile of Pentium III-M in patterns with i830M is shown by results of tests. The estimation of a gain of productivity is given concerning a pattern with processor Mobile of Pentium III 1,0 GHz.

Parsing possibilities of processors and the chip sets oriented to systems with processors of Pentium III-M, it is necessary to mark, that Intel does not refuse and the products created on the basis of kernel Coppermine. So, for example, the beginning of October, 2001 was marked by the announcement of twelve new transportable processors from Intel corporation, including Mobile Pentium III-M with kernel Tualatin.

The resulted substances testify to existence for the corporation of Intel, not gathered to concede the lead to competitors, the serious wide program on eligibility and development of transportable solutions. If now the main rate becomes on processors Mobile of Pentium III-M created on the basis of kernel Tualatin since second half of 2002, systems on the basis of transportable variants of Pentium 4 become dominating solutions step-by-step. But it already a subject for future articles.
