SUMMARY
High performance 32-bit/40-bit floating-point processor
Code compatibility—at assembly level, uses the same
instruction set as other SHARC DSPs
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 applications 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 bit of on-chip SRAM and a dedicated
4M bit of on-chip mask-programmable ROM
The ADSP-21262 is available in commercial and industrial
temperature grades. For complete ordering information,

Ordering Guide on Page46

KEY FEATURES
Serial ports offer left-justified sample-pair and I
2
S support
via 12 programmable and simultaneous receive or trans-
mit pins, which support up to 24 transmit or 24 receive I
2
S
channels of audio when all six serial ports (SPORTs) are
enabled or six full duplex TDM streams of up to 128
channels per frame
At 200 MHz (5 ns) core instruction rate, the ADSP-21262
operates at 1200 MFLOPS peak/800 MFLOPS sustained
performance whether operating on fixed- or floating-point
data
400 MMACS sustained performance at 200 MHz
Super Harvard Architecture—three independent buses for
dual data fetch, instruction fetch, and nonintrusive, zero-
overhead I/O
Transfers between memory and core at up to four 32-bit
floating- or fixed-point words per cycle, sustained
2.4G byte/s bandwidth at 200 MHz core instruction rate
and 900M byte/sec is available via DMA
