Product Summary

The adsp2100akg is an IEEE Floating-Point DSP Microprocessor optimized for digital signal processing applications. Its architecture is similar to that of Analog Devices’ adsp2100akg family of fixed-point DSP processors. Fabricated in a high-speed, low-power CMOS process, the adsp2100akg has a 30 ns instruction cycle time. With a high-performance on-chip instruction cache, the adsp2100akg can execute every instruction in a single cycle.
