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 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.
