Overview
Exynos 4412 (S5E4412) is a cost-effective, low power, performance optimized and Coretex-A9 Quad Core based processor solution for smartphone applications software.
To provide optimized hardware performance for the mobile telecommunication services and general applications on Samsung's Galaxy S3 smartphone, Exynos 4412 adopts up to 128-bit internal bus architecture, where the older A9 Cores work on 64 bits bus and many powerful hardware accelerators for different tasks. These tasks, for example are, motion video processing, Image Signal Processing, display control and scaling. Integrated Multi Format Codec (MFC) supports encoding and decoding of MPEG-2/4, H.263, H.264 and decoding of VC1. This hardware Encoder/Decoder supports real-time video conferencing and digital TV out. The memory system has dedicated DRAM ports and Static Memory port. The dedicated DRAM ports support LPDDR2 interface for high bandwidth. Static Memory Port supports NOR Flash and ROM type external memory and components. To reduce the total system cost and enhance the overall functionality, Exynos 4412 includes many hardware peripherals, such as TFT 24-bit true color LCD controller, Camera Interface, MIPI DSI, CSI-2, System Manager for power management, embedded GPS and GLONASS, MIPI slimbus interface, MIPI HSI, four UARTs, 24-channel DMA, Timers, General I/O Ports, three I2S, S/PDIF, eight IIC-BUS interface, three HS-SPI, USB Host 2.0, USB 2.0 Device operating at high speed (480Mbps), two USB HSIC, four SD Host and high-speed Multimedia Card Interface, Chip to Chip interface, and four PLLs for clock generation. Package on Package (POP) option with MCP is available for small form factor applications.
