SUMMARY
High performance 32-bit/40-bit floating-point processor
optimized for high performance audio processing
Code compatibility—at assembly level, uses the same
instruction set as other SHARC DSPs
The ADSP-21266 processes high performance audio while
enabling low system costs
Audio decoders and post processor algorithms support:
Nonvolatile memory can be configured to contain a combi-
nation of PCM 96 kHz, Dolby
Digital, Dolby Digital
Surround EX
TM
, DTS-ES
TM
Discrete 6.1, DTS-ES Matrix 6.1,
DTS
96/24 5.1, MPEG2 AAC LC, MPEG2 BC 2ch, WMA-
PRO V7.1, Dolby Pro Logic II, Dolby Pro Logic 2x, and
DTS Neo:6
TM
Various multichannel surround-sound decoders are con-
tained in ROM. For configurations of decoder algorithms,
see
Table 2 on Page 6
.
Single-instruction multiple-data (SIMD) computational archi-
tecture—two 32-bit IEEE floating-point/32-bit fixed-point/
40-bit extended precision floating-point computational
units, each with a multiplier, ALU, shifter, and register file
High bandwidth I/O—a parallel port, an SPI
port, six serial
ports, a digital audio interface (DAI), and JTAG
DAI incorporates two precision clock generators (PCGs), an
input data port (IDP) that includes a parallel data acquisi-
tion port (PDAP), and three programmable timers, all
under software control by the signal routing unit (SRU)
On-chip memory—2M bits of on-chip SRAM and a dedicated
4M bits of on-chip mask-programmable ROM
The ADSP-21266 is available with a 150 MHz or a 200 MHz
core instruction rate. For complete ordering information,
