SHARC® Processor
ADSP-21365
a
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
SUMMARY
High performance 32-bit/40-bit floating-point processor
optimized for high performance automotive audio
processing
Code compatible with all other members of the SHARC family
The ADSP-21365 is available with a 333 MHz core instruction
rate and unique audiocentric peripherals such as the digi-
tal audio interface, S/PDIF transceiver, DTCP (digital
transmission content protocol), serial ports, 8-channel
asynchronous sample rate converter, precision clock gen-
erators and more. For complete ordering information, see
Ordering Guide 53.
Audio decoder and post processor-algorithm support with
32-bit floating-point implementations
Nonvolatile 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 ESTM,
MPEG2 AAC, MPEG2 2-channel, 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
