Emerson / Mizar MZ 7776 Quad TMS320C40 Military Specification DSP Engine

The Emerson/Mizar MZ 7776 is a 6U VMEbus multiprocessor DSP engine housing four Texas Instruments SMJ320C40 military-specification processors. This quad-DSP architecture delivers 160 MFLOPS aggregate performance - 40 MFLOPS per processor at 40 MHz clock speed - optimized for parallel signal processing in demanding real-time applications. Each processor connects to six high-speed communication channels operating at 16 MB/s, enabling efficient interprocessor data exchange and scalable distributed computation across the card cage.
