The company broadcom presented the microcircuit, named in the official press release first in the branch of single-crystal solution for mobile devices, in which was united the support Of wi-Fi, Bluetooth and FM. After placing the blocks, which realize the functionality indicated, in one chip, designed for the release on the 65- nm technical process CMOS, the company revealed before the producers of mobile electronics the new possibilities of microminiaturization, reduction in the cost and energy consumption. Among the fields of application are named the cell phones, universal players and other pocket devices, it make possible to examine Web page, exchange reports, obtain and to send electronic mail, to associate  VoIP and to obtain access to other possibilities of global network with the aid of wireless connection. New product obtained the designation broadcom BCM4325. At the given moment it ensures the maximum degree of integration, uniting in one chip assemblies transceivers IEEE 802.11a/b/g, Bluetooth 2.0 + OF EDR and receiver Of fM under support Of radio data service (RDS) and Radio broadcast data service (RBDS). According to the data of producer, BCM4325 consumes to 40% less energy than the existing functional analogs. now Are accessible the test coupons Of broadcom BCM4325. There is no information about the periods for the beginning of mass deliveries and price. broadcom united one chip	Add Comment ( 0 ) BROADCOM UNITED ONE CHIP

POSTER: computer news   ||   SUPERFETCH VS READYBOOST	DATE:2007-02-06
Among the set of update , brought by the new operating system windows vista, there are two technologies intended to accelerate PC work due to the use of flash- memory: SuperFetch and ReadyBoost. The first of them works as follows: the frequently utilized system libraries and program files load in Memory, which makes possible to more rapidly start programs and to work with them. Let us say, if, after arriving in your office morning, you usually start browser, email program, messenger, text and excel , then after waiting several minutes you will see that those custom applications will begin to start noticeably faster. The basic components of the frequently utilized programs through several minutes after PC start will be already in your operational memory. The technology readyBoost consists in the growth of operational memory due to the use of flash- mmeory with interface USB 2.0. Their access time is less than in hard disks, which must give gain in the general system performance. It is necessary to note that Vista will note store in this flash-disk the critically important data , to prevent any data loss . The site toms hardware made tests of the effectiveness of technologies superFetch and ReadyBoost on contemporary system with memory volume 512 mb., 1 Gb or 2 Gb. As the test applications were used Microsoft outlook with post communications file having the volume of 1,5 Gb, Internet explorer 7, which opens locally saved web-page and text editor OpenOffice with several open documents. The following task are made : First cycle: Starting Windows vista, pause 2 minutes starting internet explorer, pause in 5 minutes (15 minutes if flash- disk with support readyBoost was connected for the first time) Starting microsoft outlook, pause 2 minutes Starting openOffice writer, pause 2 minutes Closing OpenOffice   Closing Microsoft outlook Closing Internet explorer, pause 2 minutes Second cycle: Starting internet explorer, pause 2 minutes Starting microsoft outlook, pause 2 minutes Starting openOffice writer, pause 2 minutes Closing OpenOffice Closing Microsoft outlook Closing Internet explorer The third cycle is analogous to the second. The reboot was excuted out after the completion of the third and second cycles . Without the connected flash- disk was analyzed the work Of superFetch, with it - the joint operation Of superFetch and ReadyBoost. Results can be looked on the accompanying diagrams (Microsoft and OpenOffice  , about 50 KB each). If we comment by words, then they impress. With 512 mb. OZU the time the downloading Of openOffice Of writer 2.1 and Outlook 2007 was reduced to the third time from 9-10 seconds to it was 2nd 4- x. The addition of giga-byte flash- disk makes it possible to somewhat reduce the starting time of applications (to 2-3 seconds). With growth of the volume of memory to 1 or 2 Gb the advantage from the application Of superFetch becomes already far from so explicit, although a certain acceleration nevertheless can be noted. However, as far as ReadyBoost is concerned, its benefit in the overwhelming majority of the cases can be seen only with the stopwatch, which measures the tenths of second. As a whole it is possible to make the conclusion that the new technologies are capable of accelerating work PK, especially those, which are equipped with the small volume of operational memory.

POSTER: nws   ||   SONY PORTABLE HEAD SETS	DATE:2007-02-06
The company sony presented three new models of portable head sets with the wound cable: MDR-KE30LW, MDR-Q68LW and MDR-Q38LW. All models include dynamics with the neodymium magnets and plated by copper aluminum wires (CCAW) in the coils. MDR-KE30LW will be released in four colors - black, white, violet and pink. The weight of these head sets is 28 g, diameter dynamics - 13,5 mm. communicates about the sensitivity in 104 dB/mW, the impedance, equal to 16 Ohm, and the range of the reproducible frequencies from 18 Hz to 22 kHz. The presence of carbine, which makes possible to fasten head sets to bag or bond keys, is the interesting special feature of this model. The following model, MDR-Q68LW, have already six color versions: black, white, red, silvery, dark-blue and beige. They are here used by 30- mm dynamics, the impedance of head sets - 24 Ohm, and sensitivity is 108 dB/mW. Declared range of the reproducible frequencies - from 16 Hz to 24 kHz. Weight MDR-Q68LW is equal to 43 g. MDR-Q38LW, as the previous model, includes dynamics with the diameter of 30 mm and 24 Ohm possess impedance. In this case the range of the reproducible frequencies only already - from 20 Hz to 24 kHz, and the sensitivity is equal to 104 dB/mW. Model will be released in the black, the white, the blue, the silvery, the pink and dark-blue sea (sea blue) colors. Cost MDR-KE30LW will be 26 dollars, MDR-Q68LW - 30 dollars, and MDR-Q38LW - 20 dollars. sony portable head sets	Add Comment ( 0 ) SONY PORTABLE HEAD SETS
