SHARC® Processor  
a
Preliminary Technical Data  
SUMMARY  
High performance 32-bit/40-bit floating point processor  
optimized for high performance automotive audio  
processing  
ADSP-21365/ADSP-21366  
Single-Instruction Multiple-Data (SIMD) computational  
architecture  
On-chip memory—3M bit of on-chip SRAM and a dedicated  
4M bit of on-chip mask-programmable ROM  
Code compatible with all other members of the SHARC family  
The ADSP-21365/6 is available with a 333 MHz core instruc-  
tion rate and unique audio centric peripherals such as the  
Digital Audio Interface, S/PDIF transceiver, DTCP (Digital  
Content Transmission Protocol) available on the ADSP-  
21365 only, serial ports, 8-channel asynchronous sample  
rate converter, precision clock generators and more. For  
complete ordering information, see Ordering Guide on  
page 51  
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, DTS 96/24, Neo:6, DTS ES,  
MPEG2 AAC, MPEG2 2channel, MP3, and functions like  
Bass management, Delay, Speaker equalization, Graphic  
equalization, and more. Decoder/post-processor algo-  
rithm combination support will vary depending upon the  
chip version and the system configurations. Please visit
