SUMMARY
High performance 32-bit/40-bit floating point processor
optimized for high performance audio processing
Code compatible with all other SHARC DSPs
The ADSP-21267 processes high performance audio while
enabling low system costs
Audio decoders and post processor-algorithms support.
Non-volatile memory can be configured to contain a com-
bination of PCM 96 kHz, Dolby Digital, Dolby Digital EX2,
Dolby Pro Logic IIx, DTS 5.1, DTS ES Discrete 6.1, DTS-ES
Matrix 6.1, DTS Neo:6, MPEG2x BC (2 channel) and others.
See www.analog.com/SHARC for a complete list
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, four serial
ports, a digital audio interface (DAI) and JTAG test port
DAI incorporates two precision clock generators (PCG), and
an input data port (IDP) that includes a parallel data acqui-
sition port (PDAP), and three programmable timers, all
under software control by the signal routing unit (SRU)
On-chip memory—1M Bit of on-chip SRAM and a dedicated
3M Bits of on-chip mask-programmable ROM
The ADSP-21267 is available with a 150 MHz core instruction
rate. For complete ordering information, see
