Multimedia Applications Processors

Introduction: 

The MCIMX31 and MCIMX31L multimedia applications processors represent the next step in
low-power, high-performance application processors. Unless otherwise specified, the material in this data sheet
is applicable to both the MCIMX31 and MCIMX31L processors and referred to singularly throughout this
document as MCIMX31. The MCIMX31L does not include a graphics processing unit (GPU).
Based on an ARM11™ microprocessor core, the MCIMX31 provides the performance with low power
consumption required by modern digital devices. The MCIMX31 takes advantage of the
ARM1136JF-S™ core running at up to 532 MHz, and is optimized for minimal power consumption using the
most advanced techniques for power saving (DPTC, DVFS, power gating, clock gating). With 90 nm
technology and dual-Vt transistors (two threshold voltages), the MCIMX31 provides the optimal
performance versus leakage current balance. The performance of the MCIMX31 is boosted by a
multi-level cache system, and features peripheral devices such as an MPEG-4 Hardware Encoder (VGA, 30 fps), 

an Autonomous Image Processing Unit, a Vector Floating Point (VFP11) co-processor, and a RISC-based SDMA controller.
The MCIMX31 supports connections to various types of external memories, such as DDR, NAND Flash,
NOR Flash, SDRAM, and SRAM. The MCIMX31 can be connected to a variety of external devices using
technology, such as high-speed USB2.0 OTG, ATA, MMC/SDIO, and compact flash.

Features: 
The MCIMX31 is designed for the high-tier, mid-tier smartphone markets, and portable media players.
They provide low-power solutions for high-performance demanding multimedia and graphics applications.
The MCIMX31 is built around the ARM11 MCU core and implemented in the 90 nm technology.
The systems include the following features:
• Multimedia and floating-point hardware acceleration supporting:
— MPEG-4 real-time encode of up to VGA at 30 fps
— MPEG-4 real-time video post-processing of up to VGA at 30 fps
— Video conference call of up to QCIF-30 fps (decoder in software), 128 kbps
— Video streaming (playback) of up to VGA-30 fps, 384 kbps
— 3D graphics and other applications acceleration with the ARM® tightly-coupled Vector Floating Point co-processor
— On-the-fly video processing that reduces system memory load (for example, the power-efficient viewfinder 

    application with no involvement of either the memory system or the ARM CPU)
• Advanced power management
— Dynamic voltage and frequency scaling
— Multiple clock and power domains
— Independent gating of power domains
• Multiple communication and expansion ports including a fast parallel interface to an external graphic 

   accelerator (supporting major graphic accelerator vendors)
• Security
