The TMS320DM6446AZWTA is a DaVinci Digital Media System-on-Chip leverages TIs 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. The core uses pipelining so that all parts of the processor and memory system can operate continuously.
