High performance 32-bit/40-bit floating-point processor
optimized for high precision signal processing
applications
The ADSP-21262 SHARC DSP is code compatible with all
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 computa-
tional units, each with a multiplier, ALU, shifter, and
register file
High bandwidth I/O—A parallel port, SPI port, six serial
ports, digital audio interface (DAI), and JTAG
DAI incorporates two precision clock generators (PCGs), an
input data port (IDP) which includes the parallel data
acquisition port (PDAP), and three programmable timers,
all under software control through 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
Six independent synchronous serial ports provide a variety
of serial communication protocols including TDM and I
2
S
modes
The ADSP-21262 is available with a 200 MHz core instruction
rate. For complete ordering information, see
