Design Challenges :: Operating Hours

► The Tablet System must be able to operate for “All-day” for the most

desired use case scenario.

► The biggest challenge comes in terms of the power demanded by

different peripherals and the processor of the system.

► It is absolutely a key to choose a processor which has been

designed for low power operations. Freescale’s i.MX product family

is BEST SUITED for tablet applications.

► Going beyond the traditional backlight display dimming is crucial in

meeting the long operating hours.

(17)

Design Challenges :: Software

► Must be supported with most popular BSPs. (Linux, Android …)

► Must be supported with essential Multimedia CODECs, 3D-Graphics

and application softwares.

► A great eco-system support is needed to enable the software.

► Excellent software power management is a MUST to meet long

i.MX53 IPU :: Dual Display Capabilities

► Notes

• Maximal peak rate (including blanking overhead)

Single display: 165 MP/sec

Total: 180 MP/sec

• For TV, the peak rate (and blanking overhead) is fixed by the standards:

SDTV: 13.5 MP/sec, 720p/1080i: 74.25 MP/sec, 1080p: 148.5 MP/sec

• For LCDs

The assumed screen refresh rate is 60 Hz

“Marginal support”: depends on the display, requires a more careful evaluation
