SM320DM6446-HIREL HiRel 达芬奇数字媒体片上系统

The TMS320DM6446 devices (also referenced as DM6446 and including the SM320DM6446) leverages TI’s DaVinci™ technology to meet the networked media encode and decode application processing needs of next-generation embedded devices.

The DM6446 enables OEMs and ODMs to quickly bring to market devices featuring robust operating systems support, rich user interfaces, high processing performance, and long battery life through the maximum flexibility of a fully integrated mixed processor solution.

The dual-core architecture of the DM6446 provides benefits of both DSP and Reduced Instruction Set Computer (RISC) technologies, incorporating a high-performance TMS320C64x+– DSP core and an ARM926EJ-S core.

The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data.
