ADSP-BF606/ADSP-BF607/ADSP-BF608/ADSP-BF609
The 40-bit shifter can perform shifts and rotates and is used to
support normalization, field extract, and field deposit
instructions.
The program sequencer controls the flow of instruction execu-
tion, including instruction alignment and decoding. For
program flow control, the sequencer supports PC relative and
indirect conditional jumps (with static branch prediction), and
subroutine calls. Hardware supports zero-overhead looping.
The architecture is fully interlocked, meaning that the program-
mer need not manage the pipeline when executing instructions
with data dependencies.
The address arithmetic unit provides two addresses for simulta-
neous dual fetches from memory. It contains a multiported
register file consisting of four sets of 32-bit index, modify,
length, and base registers (for circular buffering), and eight
additional 32-bit pointer registers (for C-style indexed stack
manipulation).
Blackfin processors support a modified Harvard architecture in
combination with a hierarchical memory structure. Level 1 (L1)
memories are those that typically operate at the full processor
speed with little or no latency. At the L1 level, the instruction
memory holds instructions only. The data memory holds data,
and a dedicated scratchpad data memory stores stack and local
variable information.
In addition, multiple L1 memory blocks are provided, offering a
configurable mix of SRAM and cache. The memory manage-
ment unit (MMU) provides memory protection for individual
tasks that may be operating on the core and can protect system
registers from unintended access.
The architecture provides three modes of operation: user mode,
supervisor mode, and emulation mode. User mode has
restricted access to certain system resources, thus providing a
protected software environment, while supervisor mode has
unrestricted access to the system and core resources.
INSTRUCTION SET DESCRIPTION
The Blackfin processor instruction set has been optimized so
that 16-bit opcodes represent the most frequently used instruc-
tions, resulting in excellent compiled code density. Complex
DSP instructions are encoded into 32-bit opcodes, representing
fully featured multifunction instructions. Blackfin processors
support a limited multi-issue capability, where a 32-bit instruc-
tion can be issued in parallel with two 16-bit instructions,
allowing the programmer to use many of the core resources in a
single instruction cycle.
The Blackfin processor family assembly language instruction set
employs an algebraic syntax designed for ease of coding and
readability. The instructions have been specifically tuned to pro-
vide a flexible, densely encoded instruction set that compiles to
