i.MX 6SoloLite 處理器主要特性:
• Applications processor—The processor enhances the capabilities of high-tier portable applications by fulfilling the ever increasing MIPS needs of operating systems and games. Freescale’s Dynamic Voltage and Frequency Scaling (DVFS) provides significant power reduction, allowing the device to run at lower voltage and frequency with sufficient MIPS for tasks, such as audio decode.
• Multilevel memory system—The multilevel memory system of each processor is based on the L1 instruction and data caches, L2 cache, and internal and external memory. The processor supports many types of external memory devices, including DDR3, low voltage DDR3, LPDDR2, NOR Flash, PSRAM, cellular RAM, and managed NAND, including eMMC up to rev 4.4/4.41.
• Smart speed technology—The processor has power management throughout the IC that enables the rich suite of multimedia features and peripherals to consume minimum power in both active and various low power modes. Smart speed technology enables the designer to deliver a feature-rich product, requiring levels of power far lower than industry expectations.
• Dynamic voltage and frequency scaling—The processor improves the power efficiency of devices by scaling the voltage and frequency to optimize performance.
• Multimedia powerhouse—The multimedia performance of each processor is enhanced by a multilevel cache system, NEON™ MPE (Media Processor Engine) co-processor, and a programmable smart DMA (SDMA) controller.
• Powerful graphics acceleration—Each processor provides three independent, integrated graphics processing units: 2D BLit engine, a 2D graphics accelerator, and dedicated OpenVG™ 1.1 accelerator.
• Interface flexibility—The processor supports connections to a variety of interfaces: LCD controller, CMOS sensor interface (parallel), high-speed USB on-the-go with PHY, high-speed USB host PHY, multiple expansion card ports (high-speed MMC/SDIO host and other), 10/100 Mbps Ethernet controller, and a variety of other popular interfaces (such as UART, I2C, and I2S serial audio).
• Electronic Paper Display Controller—The processor integrates EPD controller that supports E-INK color and monochrome with up to 2048 x 1536 resolution at 106 Hz refresh, 4096 x 4096 resolution at 20 Hz refresh and 5-bit grayscale (32-levels per color channel).
• Advanced security—The processor delivers hardware-enabled security features that enable secure e-commerce, digital rights management (DRM), information encryption, secure boot, and secure software downloads. The security features are discussed in detail in the i.MX 6SoloLite security reference manual (IMX6SLSRM). Contact your local Freescale representative for more information.
• Integrated power management—The processor integrates linear regulators and generate internally all the voltage levels for different domains. This significantly simplifies system power management structure.
• GPIO with interrupt capabilities—The new GPIO pad design supports configurable dual voltage rails at 1.8V and 3.3V supplies. The pad is configurable to interface at either voltage level.
