OMAP4470 app processor packs processing
power, graphics and display functions
Texas Instruments Incorporated (TI) says it newly introduced
power-efficient OMAP4470 applications processor is designed
to deliver the perfect balance between processing power,
graphics, display subsystem functionality and multilayered
user interface (UI) composition. The multicore OMAP4470
processor surpasses current market solutions with clock
speeds up to 1.8 GHz, an 80 percent increase in Web browsing
performance, increased memory bandwidth, a 2.5x boost in
graphics functionality-via the POWERVR SGX544 core from
Imagination Technologies-and a unique hardware composition
engine, claims TI. This app processor is pin-to-pin hardware
and software compatible with previously released OMAP 4
processors.
"Superior mobile computing relies on a user experience
that dwarfs all others. Fast and crisp Web browsing, HD
and liquid UIs, support for the latest applications-these
are the elements consumers judge and buy their devices on.
The OMAP4470 processor delivers the maximum experience possible
with an unmatched, power-efficient architecture," said
Remi El-Ouazzane, vice president, OMAP platform business
unit, TI.
OMAP4470 supports resolution up to QXGA (2048x1536) and
can drive still more unparalleled HD UIs with simultaneous
support for up to three HD screens and up to 2x more layered
imaging and video composition than competitive solutions,
according to TI. Features combination of a hardware composition
engine with a dedicated 2D graphics core, a display subsystem,
and dual-channel LPDDR2 memory enabling up to 7.5 GB/s of
throughput to composite the graphics and/or video data output.
This frees the GPU to perform graphics-intensive tasks such
as gaming or widget creation while the compositing process
is assigned to more power-efficient hardware subsystems.
This application processor has two ARM Cortex-A9 MPCores
running up to 1.8GHz per core and Two ARM Cortex-M3 cores.
Also features Imagination Technologies' POWERVR SGX544 GPU
for handling graphic processing.
"Graphics processing is now at the very heart of the
mobile computing experience, providing the gateway to an
enriched experience of user interface, gaming, location
services, web and media," said Hossein Yassaie, CEO,
Imagination Technologies. "Combining the OMAP 4 platform's
low-power, high-performance architecture with the extensive
acceleration capabilities and API support of Imagination's
POWERVR SGX544 will enable experiences that will really
make people sit up and take notice."
Availability: The 45nm OMAP4470 processor is expected
to sample in the second half of 2011, with devices expected
to hit the market in first half 2012. These products are
intended for high-volume mobile OEMs and ODMs, and are not
available through distributors.
