ADSP-21367 Datasheet, PDF (1/48 Pages) Analog Devices – SHARC Processor

a
Preliminary Technical Data
SUMMARY
High performance 32-bit/40-bit floating point processor
optimized for high performance automotive audio
processing
Audio decoder and post processor-algorithm support with
32-bit floating-point implementations
Non-volatile memory may be configured to support audio
decoders and post processor-algorithms like PCM, Dolby
Digital EX, Dolby Prologic IIx, Dolby Digital Plus, Dolby
headphone, DTS 96/24, Neo:6, DTS ES, DTS Lossless,
MPEG2 AAC, MPEG2 2channel, MP3, WMAPro, and Multi-
channel encoder. Functions like Bass management, Delay,
Speaker equalization, Graphic equalization, Decoder/post-
SHARC^® Processor
ADSP-21367
processor algorithm combination support will vary
depending upon the chip version and the system configu-
rations. Please visit www.analog.com
Single-Instruction Multiple-Data (SIMD) computational
architecture
On-chip memory—2M bit of on-chip SRAM and a dedicated
6M bit of on-chip mask-programmable ROM
Code compatible with all other members of the SHARC family
The ADSP-21367 is available with a 400 MHz core instruction
rate with unique audio centric peripherals such as the Digi-
tal Audio Interface, S/PDIF transceiver, serial ports, 8-
channel asynchronous sample rate converter, precision
clock generators and more. For complete ordering infor-
mation, see Ordering Guide on page 47
