ADSP-BF609 Evaluation Hardware for the ADSP-BF60x Blackfin Processor Family

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 low voltage 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.

ADSP-BF609 主要特性:

Dual-core symmetric high-performance Blackfin processor, up to 500 MHz per core

Each core contains two 16-bit MACs, two 40-bit ALUs, and a 40-bit barrel shifter

ADSP-BF609 EZ-KIT Lite® 评估系统

The ADSP-BF609 EZ-KIT Lite® is a low-cost evaluation system for the ADSP-BF60x Blackfin® processors.

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 board peripherals. Analog Devices JTAG emulators offer faster communication between the host PC and target hardware.
