2.1 Mobile solution
MT6582 is a highly integrated baseband platform incorporating both
modem and application processing and connectivity subsystems to enable 3G
smart phone applications. The chip integrates a Quad-core ARM Cortex-A7
MPCore operating up to 1.3GHz, an ARM Cortex-R4 MCU and a powerful
multistandard viedo accelerator . The MT6582 interfaces to NAND flash
memory, LPDDR2 and LPDDR3 for optimal performance and also supports
booting from SLC NAND OR EMMC to minimize the overall BOM cost. In
addition, an extensive set of interfaces are included to interface to cameras,
touch-screen displays, MMC/SD cards .
The Application processor, Quad-core ARM Cortex-A7 MPCore which
includes a NEON multimedia processing engine , offers processing power
necessary to support the latest OpenOS along with its demanding applications
such as web browsing, email, GPS navigation and games. All are viewed on a
high resolution touch screen display with graphics enhanced by the 3D graphics
acceleration. The multi-standard video accelerator and an advanced audio
subsystem are also included to provide advanced multimedia applications and
services such as streaming audio and video, a multitude of decoders and
encoders such as H.264 and MPEG-4. Audio supports include FR, EFR,
HR ,AMR RF,AMR HRand Wide-Band AMR vocoders, polyphonic ringtones
and advanced audio functions such as echo cancellation, hands-free
speakerphone operation and noise cancellation.
An ARM Cortex-R4, DSP, and 2G and 3G coprocessors provide a
powerful modem subsystem capable of supporting Category 14(21Mbps)
HSDPA downlink and Category 6 (5.76 Mbps) HSUPA uplink data rates, as well
as Class 12 GPRS , EDGE as well as Category 14(2.8Mbps) TD-HSDPA
downling and Category (2.2Mbps)TD-HSUPA uplink data rates.
