ADSP-21477 Datasheet, PDF (1/76 Pages) Analog Devices – SHARC Processor

SHARC Processor
ADSP-21477/ADSP-21478/ADSP-21479
SUMMARY
High performance 32-bit/40-bit floating-point processor
optimized for high performance audio processing
Single-instruction, multiple-data (SIMD) computational
architecture
On-chip memory—up to 5M bits of on-chip RAM, 4M bits of
on-chip ROM
Up to 300 MHz operating frequency
Qualified for automotive applications. See Automotive Prod-
ucts on Page 74
Code compatible with all other members of the SHARC family
The ADSP-2147x processors are available with unique
audio-centric peripherals, such as the digital applications
interface, serial ports, precision clock generators, S/PDIF
transceiver, asynchronous sample rate converters, input
data port, and more.
Factory programmed ROM versions containing latest audio
decoders from Dolby and DTS, available to IP licenses
