Overview
The TMS320DM6467TCUT9, produced by Texas Instruments, is a high-performance Digital Media System-on-Chip (DMSoC) that leverages TI’s DaVinci™ technology. This chip is designed to meet the networked media encode and decode digital media processing needs of next-generation embedded devices. The DM6467T 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 integration enables robust operating systems support, rich user interfaces, high processing performance, and long battery life. Although the TMS320DM6467TCUT9 is now obsolete and no longer in production, it remains a significant example of advanced digital media processing capabilities.
