The ADSP-21583 processor is part of the new, high-performance, power-efficient, real-time series that delivers greater than 24 giga-floating-point operations per second using two enhanced SHARC+® cores and advanced DSP accelerators (FFT, FIR, IIR). The ADSP-SC58x and ADSP-2158x series consume less than 2 watts, making the new processor line-up more than 5x more power efficient than previous SHARC products. This advantage provides industry leading digital signal processing performance for applications where thermal management sets the limit for power consumption, or where the higher costs and lower reliability of fans cannot be tolerated. Applications include automotive, consumer and professional audio, multi-axis motor control, and energy distribution systems.
