- enables the designer to deliver a feature-rich product that requires levels of power that are far less than typical industry expectations. Multimedia Powerhouse-The multimedia performances of the i.MX31 and i.MX31L processors are each boosted by a multi-level cache system and further enhanced by an MPEG4 hardware accelerator that provides MPEG4 SP encoding up to VGA resolution at 30 fps, as well as an Autonomous Image Processing Unit, Vector Floating Point (VFP11) co-processor, and a programmable DMA controller. Powerful Graphics Acceleration (not available in the i.MX31L)-3D graphics are the key to mobile game designs. The i.MX31 processor delivers an integrated 3D Graphics Processing Unit (GPU) that provides an incredible 0.8-0.9 MTri/sec (double textured, bi-linear, Gouraud shaded) at about 100 Mpix/sec (effective). Interface Flexibility-The i.MX31 and i.MX31L processors’ interface support connection to all popular types of external memories-DDR, SDRAM, NAND Flash, NOR Flash, SRAM, and MDOC. Designers seeking to provide products that deliver a rich multimedia experience will find a full suite of on-chip peripherals: LCD controller and CMOS sensor interface, High Speed USB On-The-Go, and two USB hosts, a multiple expansion card, and serial interfaces. There is even an ATA hard disk controller in each processor. An important design goal of the i.MX31 and i.MX31L processors is their rich and flexible connectivity support to ensure that any system configuration can be developed quickly and at minimum material cost. Increased Security-Because the need for advanced security for mobile devices continues to increase, the i.MX31 and i.MX31L processors deliver hardware-enabled security features allowing secure e-commerce, digital rights management (DRM), information encryption, secure boot, and secure software downloads. Regardless of whether you are designing a smart phone, PDA, gaming console, or other portable device, the i.MX31 and i.MX31L processors provide your design with the power and flexibility necessary for today’s competitive marketplace. 2 Features
