Overview
The TMS320DM6467, also known as the DM6467, is a high-performance Digital Media System-on-Chip (DMSoC) developed by Texas Instruments. This chip leverages TI's DaVinci™ technology to address the networked media encode and decode digital media processing needs of next-generation embedded devices. The DM6467 features a dual-core architecture, combining a TMS320C64x+ DSP core and an ARM926EJ-S core, providing the benefits of both DSP and Reduced Instruction Set Computer (RISC) technologies. This architecture enables OEMs and ODMs to quickly develop devices with robust operating systems support, rich user interfaces, high processing performance, and long battery life.
