PRELIMINARY TECHNICAL DATA  
S
a
High Performance SHARC Audio Processor  
ADSP-21266  
DAI incorporates a Precision Clock Generator (PCG), and  
an Input Data Port (IDP) that includes a Parallel Data  
Acquisition Port (PDAP), all under software control by  
the Signal Routing Unit (SRU)  
On-chip memory — 2 Mbits of on-chip SRAM and a  
dedicated 4 Mbits of on-chip mask-programmable  
ROM  
Preliminary Technical Data  
SUMMARY  
High performance 32-bit/40-bit floating point processor  
optimized for audio processing  
The ADSP-21266 processes high performance audio  
while enabling low system costs  
Audio decoder and post processor-algorithm support.  
Non-volatile memory can be configured to contain a  
combination of PCM 96kHz, Dolby Digital, Dolby  
Digital EX, DTS-ES Discrete 6.1, DTS-ES Matrix 6.1,  
DTS 96/24 5.1, MPEG2 AAC LC, MPEG2 BC 2ch, Dolby  
Pro Logic II and DTS Neo:6  
Single-Instruction Multiple-Data (SIMD) computational  
architecture—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  
Serial ports offer Left-justified Sample Pair and I2S  
support via 12 programmable and simultaneous  
receive or transmit pins, which support up to 24  
transmit or 24 receive I2S channels of audio when all  
6 Serial Ports (SPORTs) are enabled or 6 full duplex  
TDM streams of up to 128 channels per frame  
The ADSP-21266 is available with a 150 MHz or a  
200MHz core instruction rate. For complete ordering  
information, see Ordering Guide on page 43  
High bandwidth I/O — a parallel port, SPI port, 6 serial  
ports, a digital audio interface (DAI) and JTAG
