I.MX31L datasheet
I.MX31L pdf, arduino
The following techniques are used to reduce static power consumption:
• Active Well Bias (AWB)
• Power gating
• A variety of low-power modes
• Special techniques for fast wake-up times from low-power modes
The following techniques are used to reduce dynamic power consumption:
• Dynamic process and temperature compensation
• Automatic dynamic voltage frequency scaling
• Low-power clocking scheme
Features
2.3 External Memory Interface (EMI)
To allow the maximum number of potential designs, the External Memory Interface of the i.MX31 and
i.MX31L processors provide support for the following memory types:
• SRAM, NOR Flash and PSRAM—32/16-bit, Disk-On-Chip
• SDRAM, SyncFlash™, VSyncFlash™—133 MHz, 32/16-bit
• DDR—266 MHz, 32/16-bit
• NAND Flash and SmartMedia (dedicated 8-bit, shared 16-bit)
2.4 Smart Multimedia
Multimedia is one of the most important features for today’s mobile devices. The i.MX31 and i.MX31L
processors’ Smart Multimedia not only provide support, but more importantly, they provide multimedia
hardware acceleration for a wide variety of multimedia applications at performance levels that are the
equivalent of ARM11 processor performance of more than 3 GHz. The optimized hardware acceleration
enables some typical applications to operate without ARM CPU involvement—for example, the
viewfinder.
The i.MX31 and i.MX31L processors’ Smart Multimedia are able to do the following:
• Enable simultaneous MPEG4 Simple Profile (SP) video encoding and decoding.
• Support real-time video decode in any of the following advanced formats:
— MPEG4 Simple Profile (SP)
— H.264
— WMV (Windows Media™ Video)
— RV (RealVideo™)
— MPEG2
— DiVX
• Provide video and image data pre/post-processing (resizing, color conversion, filtering) that is fully
hardware accelerated.
