GENERAL DESCRIPTION
The ADSP-BF561 processor is a high-performance member of
the Blackfin family of products targeting a variety of multimedia
and telecommunications applications. At the heart of this device
are two independent Analog Devices Blackfin processors. These
Blackfin processors combine a dual-MAC state-of-the-art signal
processing engine, the advantage of a clean, orthogonal RISC-
like microprocessor instruction set, and single-instruction, mul-
tiple-data (SIMD) multimedia capabilities into a single
instruction-set architecture. The ADSP-BF561 device integrates
a general purpose set of digital imaging peripherals creating a
complete system on-chip solution for digital imaging and multi-
media applications.
The ADSP-BF561 processor has 328 KBytes of on-chip mem-
ory. Each Blackfin core includes:
16K Bytes of Instruction SRAM/Cache
16K Bytes of Instruction SRAM
32K Bytes of Data SRAM/Cache
32K Bytes of Data SRAM
4K Bytes of Scratchpad SRAM
Additional on-chip memory peripherals include:
128 KBytes of Low Latency On-chip SRAM
Four Channel Internal Memory DMA Controller
External Memory controller with glueless support for
SDRAM, SRAM, and Flash
PORTABLE LOW-POWER ARCHITECTURE
Blackfin processors provide world-class power management
and performance for embedded signal processing applications.
Blackfin processors are designed in a low power and low voltage
design methodology and feature Dynamic Power Management.
Dynamic Power Management is the ability to vary both the volt-
age and frequency of operation to significantly lower the overall
power dissipation. This translates into an exponential reduction
in power dissipation providing longer battery life to portable
applications.
BLACKFIN PROCESSOR CORE
As shown in
Figure 2
, each Blackfin core contains two multi-
plier/accumulators (MACs), two 40-bit ALUs, four video ALUs,
and a single shifter. The computational units process 8-bit, 16-
bit, or 32-bit data from the register file.
