GENERAL DESCRIPTION
The ADSP-BF512/ADSP-BF512F, ADSP-BF514/ADSP-
BF514F, ADSP-BF516/ADSP-BF516F, ADSP-BF518/ADSP-
BF518F processors are members of the Blackfin
family of prod-
ucts, incorporating the Analog Devices/Intel Micro Signal
Architecture (MSA). Blackfin processors combine a dual-MAC
state-of-the-art signal processing engine, the advantages of a
clean, orthogonal RISC-like microprocessor instruction set, and
single-instruction, multiple-data (SIMD) multimedia capabili-
ties into a single instruction-set architecture.
The processors are completely code compatible with other
Blackfin processors.
By integrating a rich set of industry-leading system peripherals
and memory, Blackfin processors are the platform of choice for
next-generation applications that require RISC-like program-
mability, multimedia support, and leading-edge signal
processing in one integrated package.
PORTABLE LOW POWER ARCHITECTURE
Blackfin processors provide world-class power management
and performance. They are produced with a low power and low
voltage design methodology and feature on-chip dynamic
power management, which is the ability to vary both the voltage
and frequency of operation to significantly lower overall power
consumption. This capability can result in a substantial reduc-
tion in power consumption, compared with just varying the
frequency of operation. This allows longer battery life for
portable appliances.
SYSTEM INTEGRATION
The ADSP-BF51x processors are highly integrated system-on-a-
chip solutions for the next generation of embedded network
connected applications. By combining industry-standard inter-
faces with a high performance signal processing core, cost-
effective applications can be developed quickly, without the
need for costly external components. The system peripherals
include an IEEE-compliant 802.3 10/100 Ethernet MAC with
IEEE-1588 support (ADSP-BF518/ADSP-BF518F only), an RSI
controller, a TWI controller, two UART ports, two SPI ports,
two serial ports (SPORTs), nine general-purpose 32-bit timers
(eight with PWM capability), 3-phase PWM for motor control,
a real-time clock, a watchdog timer, and a parallel peripheral
interface (PPI).
BLACKFIN PROCESSOR CORE
As shown in Figure 1, the Blackfin processor core contains two
16-bit multipliers, two 40-bit accumulators, two 40-bit ALUs,
four video ALUs, and a 40-bit shifter. The computation units
process 8-, 16-, or 32-bit data from the register file.
The compute register file contains eight 32-bit registers. When
performing compute operations on 16-bit operand data, the
register file operates as 16 independent 16-bit registers. All
operands for compute operations come from the multiported
register file and instruction constant fields.
Each MAC can perform a 16-bit by 16-bit multiply in each
cycle, accumulating the results into the 40-bit accumulators.
Signed and unsigned formats, rounding, and saturation
are supported.
The ALUs perform a traditional set of arithmetic and logical
operations on 16-bit or 32-bit data. In addition, many special
instructions are included to accelerate various signal processing
tasks. These include bit operations such as field extract and pop-
ulation count, modulo 232 multiply, divide primitives, saturation
and rounding, and sign/exponent detection. The set of video
instructions include byte alignment and packing operations,
16-bit and 8-bit adds with clipping, 8-bit average operations,
and 8-bit subtract/absolute value/accumulate (SAA) operations.
The compare/select and vector search instructions are also
provided.
