ADI’s ADSP-BF609 is a Blackfin dual-core processor with an operating frequency of up to 1GHz, and the hardware supports high-definition video analysis. ADSP-BF609 adopts ADI/INTEL Micro Signal Architecture (MSA), each core contains two 16-bit MAC, two 40 Bit ALU and 40-bit barrel shift RISC-like register and instruction modes with advanced debug, trace and performance monitoring, mainly used in applications ranging from automotive electronics to embedded industrial, instrumentation and motor control. This article introduces the ADSP-BF609 Key Features, Block Diagram, Blackfin Processor Core Block Diagram and ADSP-BF609 EZ-KIT Lite® Evaluation System Key Features, Block Diagram, Circuit Diagram, and Bill of Materials.

The ADSP-BF609 processor is a member 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 processor offers performance up to 500 MHz, as well as low static power consumption. Produced with a low-power and lowvoltage design methodology, they provide world-class power management and performance.

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 programmability, multimedia support, and leadingedge signal processing in one integrated package. These applications span a wide array of markets, from automotive systems to embedded industrial, instrumentation and power/motor control applications.

BLACKFIN processor core

The processor integrates two Blackfin processor cores. Each 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 population 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.

Also provided are the compare/select and vector search instructions. For certain instructions, two 16-bit ALU operations can be performed simultaneously on register pairs (a 16-bit high half and 16-bit low half of a compute register). If the second ALU is used, quad 16-bit operations are possible.

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 execution, 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 programmer need not manage the pipeline when executing instructions with data dependencies.

The address arithmetic unit provides two addresses for simultaneous 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 pointers 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 management 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.

ADSP-BF609 EZ-KIT Lite® Evaluation System

The ADSP-BF609 processor is a member 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.

ADSP-BF60x Blackfin processors embody a new type of embedded processor designed specifically to meet the computational demands and power constraints of today’s automotive systems, embedded industrial, instrumentation, and power/motor control applications.

The evaluation board is designed to be used in conjunction with the CrossCore® Embedded Studio (CCES) development tools to test capabilities of the ADSP-BF60x Blackfin processors. The CCES development environment aids advanced application code development and debug, such as:

• Create, compile, assemble, and link application programs written in C++, C, and assembly

• Load, run, step, halt, and set breakpoints in application programs

• Read and write data and program memory

• Read and write core and peripheral registers

• Plot memory

Access to the processor from a personal computer (PC) is achieved through a USB port (when a debug agent is mounted on the EZ-KIT Lite board) or an external JTAG emulator. The USB interface provides unrestricted access to the ADSP-BF609 processor and evaluation peripheral boards. Analog Devices JTAG emulators offer faster communication between the host PC and target hardware. Analog Devices carries a wide range of in-circuit emulation products.
