SHARC^®

Embedded Processor

ADSP-21266

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

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,

see Ordering Guide on Page 44.

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^TMDiscrete 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.
