1 INTRODUCTION TO SHARC
PROCESSORS
This chapter briefly describes the SHARC processor’s architecture and key
features and compares available models.
Topics include:
•“What are SHARC Processors?” on page 1-1
•“Four Generations of SHARC Processors” on page 1-5
What are SHARC Processors?
SHARC is the name of a family of high performance 32-bit floating-point
processors based on a Super Harvard Architecture. SHARC processors
dominate the floating-point digital signal processing market, delivering
exceptional core and memory performance complemented by outstanding
I/O throughput. The industry standard SHARC family makes float-
ing-point processing economical for applications where performance and
dynamic range are key considerations such as home, professional, and
automotive audio, medical, and industrial and instrumentation products.
The SHARC processor portfolio currently consists of four generations of
products providing code-compatible solutions, ranging from entry-level
products priced at less than $10 to the highest performance products
offering fixed- and floating-point computational power to 450 MHz/2700
MFLOPs. Regardless of the specific product choice, all SHARC processors
provide a common set of features and functionality usable across many
signal processing markets and applications. This baseline functionality

What are SHARC Processors?
1-2 Getting Started With SHARC Processors
enables the SHARC user to leverage legacy code and design experience,
while transitioning to higher-performance, more highly-integrated
SHARC products.
By integrating on-chip, single-instruction, multiple-data (SIMD) process-
ing elements, SDRAM, and I/O peripherals, SHARC processors deliver
breakthrough signal processing performance.
SHARC Applications
The combination of a high performance core surrounded by appropriate
peripherals, a large software library, and award-winning development tools
makes SHARC processors the ideal choice for audio and broad market
processor applications. Here are some applications:
•Home theater/digital home applications. The ADSP-21266,
ADSP-21365, ADSP-21366, ADSP-21367, ADSP-21467,
ADSP-21483, ADSP-21486, and ADSP-21487 processors enable
highly efficient software implementations of audio decode and
postprocessing algorithms, such as Dolby® Digital, Dolby Digital
EX, DTS-ES Discrete 6.1, DTS-ES Matrix 6.1, DTS 96/24™ 5.1,
DTS-HD, DTS Express, MPEG-2 AAC LC, MPEG-2 BC 2ch,
Dolby Pro Logic II, Dolby Pro Logic 2x, Dolby True HD, DTS
Neo:6, DDPlus DCV, Neural Audio, Audyssey room equalization,
and WMA Pro. Libraries of all standard—and many proprietary—
audio algorithms reside in on-chip ROM, eliminating the need for
external ROM.
•Professional audio applications. A number of third generation
(ADSP-2136x) and fourth generation (ADSP-2146x) SHARC pro-
cessors are well-suited for professional audio applications requiring
high processing power and advanced on-chip peripherals such as
sample rate conversion, S/PDIF transmitter/receiver, and BGA and
LQFP package options.

Introduction to SHARC Processors
•Automotive audio applications. The ADSP-21362, ADSP-21365,
ADSP-21369, ADSP-21371, ADSP-21462, ADSP-21465,
ADSP-21469, ADSP-21472, ADSP-21475, and ADSP-21479
processors, with integration of sample-rate conversion, DTCP
cipher, precision clock generators, and serial ports, are ideal choices
for new multichannel automotive audio designs.
•Broad market use. SHARC processors are available in commercial,
industrial, and automotive temperature grade packages. They are
used in a wide variety of signal processing applications, providing
up to 450 MHz performance in a single-instruction, multiple-data
architecture (SIMD). Applications include imaging, medical
devices, communications, military, test equipment, 3-D graphics,
speech recognition, and motor control.
Architecture Overview
This section describes architectural features of the SHARC processor.
Super Harvard Architecture
The 32-bit floating-point SHARC processors from Analog Devices are
based on a Super Harvard Architecture that balances exceptional core and
memory performance with outstanding I/O throughput capabilities. This
architecture extends the original concepts of separate program and data
memory buses by adding an I/O processor with its associated dedicated
buses.
In addition to satisfying the demands of the most computationally-inten-
sive, real-time signal processing applications, SHARC processors integrate
large memory arrays and application-specific peripherals designed to sim-
plify product development and reduce time to market.

What are SHARC Processors?
1-4 Getting Started With SHARC Processors
Common Architectural Features
SHARC processors share the following architectural features.
• 32/40-bit IEEE floating-point math
• 32-bit fixed-point multipliers with 64-bit product and 80-bit accu-
mulation
• No arithmetic pipeline. All computations are single cycle.
• Circular buffer addressing supported in hardware
• Sixteen address pointers supporting 16 circular buffers
• Six nested levels of zero-overhead looping in hardware
• Rich algebraic assembly language syntax
• Conditional arithmetic, bit manipulation, divide and square root,
bit field deposit and extract supported by instruction set
• Zero-overhead background transfers at full clock rate without pro-
cessor intervention
In the core, every instruction can execute in a single cycle. The buses and
instruction cache provide rapid unimpeded data flow to the core to main-
tain the execution rate.
Figure 1-1 shows a detailed block diagram of a single core SHARC 32-bit
processor and the I/O processor (IOP). It illustrates the following archi-
tectural features:
• Two processing elements (PEx and PEy), each containing 32-bit
IEEE floating-point computation units—multiplier, arithmetic
logic unit (ALU), shifter, and data register file
• Program sequencer with related instruction cache, interval timer,
and data address generators (DAG1 and DAG2)

Getting Started With SHARC Processors 1-5
Introduction to SHARC Processors
• An SDRAM controller that provides an interface to as many as four
separate banks of industry-standard SDRAM devices
• Up to a maximum of 5M bits of on-chip SRAM and up to 4M bits
of on-chip, mask-programmable ROM
• Input/output processor (IOP) with integrated direct memory
access (DMA) controller, serial peripheral interface (SPI) compati-
ble port, and serial ports (SPORTs) for point-to-point
multiprocessor communications
• A variety of audio-centric peripheral modules including a
Sony/Philips digital interface (S/PDIF), sample rate converter
(SRC), and pulse width modulation (PWM)
• JTAG test access port for emulation
Figure 1-1 also shows the three on-chip buses of the
ADSP-21472/21475/21479 processors: the PM bus, DM bus, and I/O
bus. The PM bus provides access to instructions or data. During a single
cycle, these buses let the processor access two data operands from memory,
access an instruction (from cache), and perform a DMA transfer. In addi-
tion, Figure 1-1 shows the asychronous memory interface available on the
ADSP-2147x processors.
Four Generations of SHARC Processors
The SHARC architecture has a long history in the floating-point proces-
sor market. While architectural enhancements have been made with each
successive processor generation, the common traits of exceptional float-
ing-point performance, matched to high-bandwidth memory and I/O
transfers, remains. All four generations of SHARC processors are still in
production, offering a variety of code-compatible options to meet a wide
array of price, performance, and footprint requirements.

What are SHARC Processors?
1-6 Getting Started With SHARC Processors
First generation SHARC products offer performance of up to
66 MHz/198 MFLOPS and form the cornerstone of the SHARC proces-
sor family. Their easy-to-use instruction set architecture that supports
both 32-bit fixed-point and 32/40-bit floating-point data formats, com-
bined with large memory arrays and sophisticated communications ports,
make them suitable for a wide array of parallel processing applications
including consumer audio, medical imaging, military, industrial, and
instrumentation.
Second generation SHARC products double the level of signal processing
performance (100 MHz/600 MFLOPS) by utilizing a single-instruction,
multiple-data (SIMD) architecture. This hardware extension doubles the
number of computational resources available to the system programmer.
Second generation products contain dual multipliers, ALUs, shifters, and
data register files, significantly increasing overall system performance in a
