GENERAL DESCRIPTION
The ADSP-21469 SHARC® processor is a member of the SIMD
SHARC family of DSPs that feature Analog Devices’ Super Har-
vard Architecture. The processor is source code compatible with
the ADSP-2126x, ADSP-2136x, ADSP-2137x, and ADSP-2116x
DSPs, as well as with first generation ADSP-2106x SHARC pro-
cessors in SISD (single-instruction, single-data) mode. The
processor is a 32-bit/40-bit floating point processor optimized
for high performance audio applications with its large on-chip
SRAM, multiple internal buses to eliminate I/O bottlenecks, and
an innovative digital applications interface (DAI).
Table 1 shows performance benchmarks for the ADSP-21469
processor, and Table 2 shows the product’s features.

1 Audio decoding algorithms include PCM, Dolby Digital EX, Dolby Pro Logic IIx,
DTS 96/24, Neo:6, DTS ES, MPEG-2 AAC, MP3, and functions like bass
management, delay, speaker equalization, graphic equalization, and more.
Decoder/postprocessor algorithm combination support varies depending upon
the chip version and the system configurations. Please visit www.analog.com for
complete product information and availability.
2 These products contain the Digital Transmission Content Protection protocol, a
proprietary security protocol. Contact your Analog Devices sales office for more
information.
Figure 1 on Page 1 shows the two clock domains that make up
the ADSP-21469 processors. The core clock domain contains
the following features:
• Two processing elements (PEx, PEy), each of which com-
prises an ALU, multiplier, shifter, and data register file
• Data address generators (DAG1, DAG2)
• Program sequencer with instruction cache
• One periodic interval timer with pinout
• PM and DM buses capable of supporting 2 × 64-bit data
transfers between memory and the core at every core pro-
cessor cycle
• On-chip SRAM (5M bit)
• On-chip mask-programmable ROM (4M bit)
• JTAG test access port for emulation and boundary scan.
The JTAG provides software debug through user break-
points which allows flexible exception handling.
Figure 1 on Page 1 also shows the peripheral clock domain (also
known as the I/O processor) which contains the following
features:
• IOD0 (peripheral DMA) and IOD1 (external port DMA)
buses for 32-bit data transfers
• Peripheral and external port buses for core connection
• External port with an AMI and DDR2 controller
• 4 units for PWM control
• 1 MTM unit for internal-to-internal memory transfers
