GENERAL DESCRIPTION
The ADSP-BF531/2/3 processors are members of the Blackfin
family of products, 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 capabilities into a single instruction-set
architecture.
The ADSP-BF531/2/3 processors are completely code and pin
compatible, differing only with respect to their performance and
on-chip memory. Specific performance and memory configura-
tions are shown in
Table 1
.
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. Blackfin processors are designed in a low
power and low voltage design methodology and feature
Dynamic Power Management, the ability to vary both the volt-
age and frequency of operation to significantly lower overall
power consumption. Varying the voltage and frequency can
result in a substantial reduction in power consumption, com-
pared with just varying the frequency of operation. This
translates into longer battery life for portable appliances.
SYSTEM INTEGRATION
The ADSP-BF531/2/3 processors are highly integrated system-
on-a-chip solutions for the next generation of digital communi-
cation and consumer multimedia applications. By combining
industry-standard interfaces with a high performance signal
processing core, users can develop cost-effective solutions
quickly without the need for costly external components. The
system peripherals include a UART port, an SPI port, two serial
ports (SPORTs), four general-purpose timers (three with PWM
capability), a real-time clock, a watchdog timer, and a Parallel
Peripheral Interface.
ADSP-BF531/2/3 PROCESSOR PERIPHERALS
The ADSP-BF531/2/3 processor contains a rich set of peripher-
als connected to the core via several high bandwidth buses,
providing flexibility in system configuration as well as excellent
overall system performance (see the functional block diagram in
Figure 1 on Page 1
). The general-purpose peripherals include
functions such as UART, Timers with PWM (Pulse-Width
Modulation) and pulse measurement capability, general-pur-
pose flag I/O pins, a Real-Time Clock, and a Watchdog Timer.
This set of functions satisfies a wide variety of typical system
support needs and is augmented by the system expansion capa-
bilities of the part. In addition to these general-purpose
peripherals, the ADSP-BF531/2/3 processor contains high speed
serial and parallel ports for interfacing to a variety of audio,
video, and modem codec functions; an interrupt controller for
flexible management of interrupts from the on-chip peripherals
or external sources; and power management control functions
to tailor the performance and power characteristics of the pro-
cessor and system to many application scenarios.
All of the peripherals, except for general-purpose I/O, Real-
Time Clock, and timers, are supported by a flexible DMA struc-
ture. There is also a separate memory DMA channel dedicated
to data transfers between the processor's various memory
spaces, including external SDRAM and asynchronous memory.
Multiple on-chip buses running at up to 133 MHz provide
enough bandwidth to keep the processor core running along
with activity on all of the on-chip and external peripherals.
The ADSP-BF531/2/3 processor includes an on-chip voltage
regulator in support of the ADSP-BF531/2/3 processor
Dynamic Power Management capability. The voltage regulator
provides a range of core voltage levels from a single 2.25 V to
3.6 V input. The voltage regulator can be bypassed at the user's
discretion.
BLACKFIN PROCESSOR CORE
As shown in
Figure 2 on Page 5
, 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 compu-
tation units process 8-bit, 16-bit, 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 2
