Qualcomm chips kernel ARM - from phones to laptops

February 17, 2009, 1:10 pm

   The company Qualcomm has announced four new mobile SoC, three of which are based on processor core Scorpion, an appropriate architecture ARMv7. The fourth chip, MSM7227, built on the basis of ARM11 applications processor and, despite the greater the number of kernels, is a simpler solution, targeted for use in smartphones lower price range, while the MSM8260, MSM8660 and MSM8270 are aimed at high-level device with support for high definition video and not just smart phones, and even laptops.
MSM7227 is an evolution of the two years ago, MSM7225, repeating its size (12 x 12 mm) and maintaining consistency of contact, which provides designers the opportunity to further develop the existing developments. Working frequency ARM11 core in MSM7227 increased to 600 MHz (against 528 MHz of the predecessor), the core of the signal processor (DSP) operating at 320 MHz, and the nucleus of the communications processor - at a frequency of 400 MHz. As before, there are features hardware acceleration of graphics and coding/decoding video WQVGA with frequency 30 frames per second and support for GPS, but now supported by the camera modules with up to 8-megapixel (v. 5), and the realization had grown up with a Bluetooth version 2. 0 to 2. 1.
The manufacturer said that the MSM7227 is reduced compared with the MSM7225 level of energy consumption, but did not provide any quantitative estimates of the improvements. Affirming also compatible with most common mobile operating systems, including Android, Symbian S60, Windows Mobile, and BREW Mobile Platform.
announced details about the technical details of MSM8260, MSM8660 and MSM8270 yet few know that chips are manufactured on 45-nm standard kernel applications Scorpion processor operates at a frequency of 1, 2 GHz, the core DSP - 600 MHz, supports recording and playback video format full 1080p. Maximum resolution image - up to 1280 x 960 pixels, which is consistent with the performance of notebooks, cameras modules are supported with up to 16 megapixel, and surround sound playback in the format of 5. 1. Separately, it can be noted in the series appeared MSM8xxx support of the Russian satellite navigation system GLONASS, in addition to the American GPS.
Major differences between the chipsets MSM8xxx is supported by various standards to high-speed data - for the MSM8260 is 3GPP Release 7 HSPA (bandwidth up to 28 Mbps), the MSM8660 is added multirezhimnaya support 3GPP/3GPP2, and MSM8270, in addition, supports Standard Release 8 dual-carrier HSPA (up to 42 Mbit/s).
According to Qualcomm, the shipment of samples MSM8260 and MSM8660 will begin in the fourth quarter of this year, and the MSM8270 - by mid-2010, With respect to the MSM7227, that prototypes of these chips have already started to spread, and this year we expect the emergence of smartphones to its base.
