Product Summary

The SMJ320C30GBM40Q is a digital signal processor (DSP) device. The SMJ320C30GBM40Q supports a wide range of digital signal processing applications such as tactical communications, guidance, military modems, speech processing, spectrum analysis, audio processing, digital filtering, high-speed control, graphics, and other computation-intensive applications. The SMJ320C30GBM40Q has a 100-ns instruction cycle time. With these fast instruction cycle times and their innovative memory configurations, the device performs operations necessary for many real-time digital signal processing algorithms. Since most instructions require only one cycle, the SMJ320C30GBM40Q is capable of executing 12.5 million instructions per second.
