Overview
The TMS320DM368ZCEDF from Texas Instruments is a high-performance Digital Media System-on-Chip (DMSoC) designed for advanced video processing applications. This device is part of the DaVinci video processor family and is capable of achieving HD video processing at 1080p 30fps H.264. It features an ARM926EJ-S core running at 432 MHz, which supports both 32-bit and 16-bit (Thumb® mode) instruction sets. The DM368 is pin-to-pin and software compatible with the DM365 processors, making it an ideal choice for developers looking to upgrade or maintain consistency across different projects.
The device includes a range of peripherals and interfaces, such as DDR2/mDDR memory controllers, USB 2.0 OTG, 10/100 Mb/s Ethernet MAC, and multiple SPI, UART, and I2C interfaces. It also supports various video codecs including H.264, MPEG-4, MPEG-2, MJPEG, and VC1/WMV9, which are handled by independent coprocessors (HDVICP and MJCP), offloading compression tasks from the main ARM core.
