Getting Started with ADSP-BF70x Processors


ADSP-BF70x Processors


The ADSP-BF70x Blackfin processor series is a high-performance DSP family that delivers a class-leading  800 MMACS of processing power at less than 100mW. The cost-effective eight-member series includes up to 1MB of internal SRAM, eliminating external memory in many applications, while a second configuration features an optional DDR memory interface. Using the enhanced Blackfin+ core, the combination of performance, power efficiency, memory integration, security, and value allows designers to incorporate advanced 16- and 32-bit processing into a range of new use cases, including industrial imaging and building controls as well as portable and automotive audio. The ADSP-BF70x series offers designers unparalleled flexibility and functionality through an array of advanced connectivity options (including USB, SDIO, CAN, ePPI, SPORT, QuadSPI) while enabling bus-powered applications and extending the life of battery-powered devices.


You can learn more about our latest Blackfin processor family on our ADSP-BF70x series product page.

What is required in order to evaluate the ADSP-BF70x Processors?


CrossCore® Embedded Studio (CCES) is a world-class integrated development environment (IDE) for the Analog Devices Blackfin® and SHARC® processor families.  This Eclipse™ based, highly visual IDE enables seamless, intuitive code generation and debug support.  A highly integrated IDE, CrossCore® Embedded Studio is optimized for popular Micrium add-in components including real time operating systems (RTOS), USB and file system stacks. There is also integrated support for a TCP/IP stack. The IDE is combined with Analog Devices advanced optimizing compiler technology and supports standards such as ISO/IEC C and C++, MISRA-C, Embedded C and MCAPI, plus additional development features to get your product to market even sooner.


Further information can be found on the CCES product page and the Getting Started with CCES guide.



The ADSP-BF70x evaluation hardware provides a low cost hardware solution for users to evaluate the Analog Devices ADSP-BF70x processor family.

Release Note


    • The ADSP-BF707 EZ-Board can also be purchased separately, if an ICE-1000 or ICE-2000 emulator is already available to the user.


The ADSP-BF707 EZ-Board Design Database contains all of the electronic information required for the design, layout, fabrication and assembly of the ADSP-BF707 EZ-Board, and is available to download from the Product Downloads area.



The ADSP-BF707 Board Support Package is free to download and use, and does not require a separate license to be installed in CCES.  It provides comprehensive software support for the ADSP-BF707 EZ-Board. Specifically, drivers, examples and code sketches are included for the following components:

    • INA230 current-shunt and power monitor ADC driver
    • INA3221 shunt and bus voltage monitor ADC driver


It also provides comprehensive examples which demonstrate the on-chip drivers and services. 


NOTE: A fast functional simulator supporting ADSP-BF70x processors is also available as part of CCES, details of which can be found here.



How do I begin evaluating the ADSP-BF70x Processors?



When starting CCES for the first time, you will be prompted to install a license. Click ‘Yes’ to install a license and then, in the “Select License Type” window:


    • to begin a 90 day evaluation of CCES, select ‘I do not have a serial number and would like to evaluate the product, and in the “Select license activation method’ window select ‘Install and activate a license on-line all in one step’. Upon clicking ‘Finish’, your evaluation license will be activated and your 90 day evaluation period will begin.


For further information on installing a license see the following FAQ:

How can I obtain and install evaluation and full licenses for CrossCore Embedded Studio?


  • Purchase the ADSP-BF707 EZ-KIT Lite or EZ-Board
  • Install the ADSP-BF707 EZ-Board Support Package.


NOTE: A fast functional simulator supporting ADSP-BF70x processors is also available as part of CrossCore Embedded Studio. Simulation is supported for the following components:

    • Instruction set and core machine state
      • excludes pipeline, cache, and branch predictor
    • Core event controller
    • Internal and external memory spaces
    • Utility ROM images in L2 ROM space
    • Core timer


Addition system components and peripherals will be supported in the simulator in future releases. More information can be found here.

  • Examples and Sketches

The ADSP-BF70x EZ-Board Support Package and CCES include a number of code sketches and examples, a list of which can be found by going to CCES Help->Browse Examples. Code sketches are small code fragments, which can be generated with parameterized input provided by the user in CrossCore Embedded Studio. The resulting code can then be copied and pasted into a project.


The examples include Device Driver and System Services examples for a variety of peripherals and the Power-On Self Test demo, which tests the many peripherals of the ADSP-BF707 EZ-Board and is pre-programmed on the EZ-KIT during production.
