REV. A
The powerful 40-bit shifter has extensive capabilities for perform-
ing shifting, rotating, normalization, extraction, and for
depositing data.
The data for the computational units is found in a multiported
register file of sixteen 16-bit entries or eight 32-bit entries.
A powerful program sequencer controls the flow of instruction
execution, including instruction alignment and decoding. The
sequencer supports conditional jumps and subroutine calls, as
well as zero-overhead looping. A loop buffer stores instructions
locally, eliminating instruction memory accesses for tightly
looped code.
Two data address generators (DAGs) provide addresses for
simultaneous dual operand fetches from memory. The DAGs
share a register file containing four sets of 32-bit Index, Modify,
Length, and Base registers. Eight additional 32-bit registers
provide pointers for general indexing of variables and stack
locations.
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. Level 2 (L2) memories are other
memories, on-chip or off-chip, that may take multiple processor
cycles to access. At the L1 level, the instruction memory holds
instructions only. The two data memories hold data, and a
dedicated scratch pad data memory stores stack and local variable
information. At the L2 level, there is a single unified memory
space, holding both instructions and data.
In addition, the L1 instruction memory and L1 data memories
may be configured as either Static RAMs (SRAMs) or caches.
The Memory Management Unit (MMU) provides memory pro-
tection for individual tasks that may be operating on the core and
may 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.
The Blackfin processor instruction set has been optimized so that
16-bit op-codes represent the most frequently used instructions,
resulting in excellent compiled code density. Complex DSP
instructions are encoded into 32-bit op-codes, representing fully
featured multifunction instructions. Blackfin processors support
a limited multiple issue capability, where a 32-bit instruction 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 assembly language uses an algebraic
syntax for ease of coding and readability. The architecture has
been optimized for use in conjunction with the C/C++ compiler,
resulting in fast and efficient software implementations.
Memory Architecture
The ADSP-BF535 Blackfin processor views memory as a single
unified 4 Gbyte address space, using 32-bit addresses. All
resources, including internal memory, external memory, PCI
address spaces, and I/O control registers, occupy separate
sections of this common address space. The memory portions of
this address space are arranged in a hierarchical structure to
provide a good cost/performance balance with very fast, low
latency memory as cache or SRAM very close to the processor;
and larger, lower cost, and lower performance memory systems
farther away from the processor. See Figure 2.

1 THE ADDRESSES SHOWN FOR THE SDRAM BANKS REFLECT A FULLY
POPULATED SDRAM ARRAY WITH 512M BYTES OF MEMORY. IF ANY BANK
CONTAINS LESS THAN 128M BYTES OF MEMORY, THAT BANK WOULD
EXTEND ONLY TO THE LENGTH OF THE REAL MEMORY SYSTEMS, AND THE
END ADDRESS WOULD BECOME THE START ADDRESS OF THE NEXT BANK.
THIS WOULD CONTINUE FOR ALL FOUR BANKS, WITH ANY REMAINING SPACE
BETWEEN THE END OF MEMORY BANK 3 AND THE BEGINNING OF ASYNC
MEMORY BANK 0, AT ADDRESS 0x2000 0000, TREATED AS RESERVED
ADDRESS SPACE.
