Texas Instruments SMJ320C80 Digital Signal Processor SMJ320C80HFHM50

The SMJ320C80 is a single-chip, MIMD parallel digital signal processor designed for high-performance applications. It features a 32-bit RISC master processor capable of executing over two billion operations per second, along with four parallel 32-bit DSPs that enhance its processing capabilities. The device includes a transfer controller that supports off-chip data transfer rates of up to 400 MBps and a video controller for managing video timing and VRAM control. The processor is equipped with a 4K-byte instruction cache and a 4K-byte data cache for the master processor, while each parallel processor has a 2K-byte instruction cache and 8K-byte data RAM. It operates with a 20-ns cycle time and supports both big and little-endian data formats. The SMJ320C80 is suitable for applications in video, imaging, and high-speed telecommunications, with an operating temperature range of -55¬8C to 125¬8C for military-grade versions and -40¬8C to 85¬8C for industrial versions.
