The Blackfin Low-power Imaging Platform (BLIP) is a low cost, low power embedded computer vision platform targeting a vast array of real-time sensing applications. BLIP leverages the latest entry within the industry-leading, low power Blackfin processor family as well as Analog Devices’ optimized software library deliverables. This solution offers end equipment manufacturers an out of the box form factor development platform with multiple functional profiles covering intelligent motion sensing, people counting, vehicle detection, and face detection deployable in both indoor and outdoor use cases. The BLIP system includes an intuitive configuration GUI and enables real-time analysis of captured video, as well as video output/display through an on-board USB port, making it a highly valuable tool for product development. Additionally, the associated documentation package is well positioned to help customers accelerate their time to market.

The ADSP-BF707 evaluation hardware provides a low cost hardware solution for users to evaluate the Analog Devices ADSP-BF70x Blackfin processor family. 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. New enhancements to the Blackfin+^™ core add 32-bit MAC and 16-bit complex MAC support, cache enhancements, branch prediction and other instruction set improvements—all while maintaining instruction set compatibility to previous Blackfin products.

The ADSP-BF707 EZ-KIT Lite includes all hardware necessary to immediately being evaluation:

• The ADS P- BF707 EZ-Board ™
• CE-approved power supply
• The ADZS-ICE-1000 emulator
• USB cable

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

The ADSP-BF707 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 Products Download area on this page.

The evaluation hardware is designed to be used in conjunction with the CrossCore^® Embedded Studio (CCES) software development tools to test capabilities of the ADSP-BF70x 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

The ADSP-BF707 Board Support Package, available to download from this page, 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

New debug feature added for the ICE-1000/ICE-2000:

• Coresight Serial Wire Debug (SWD) 

The 24 GHz radar sensor platform called Demorad is a novel microwave radar evaluation platform solution with out-of-the-box software examples and easy startup of radar sensor all done within minutes. Demorad platform enables rapid product prototyping aimed at R&D interests in investigating radar and developing radar sensor products that can measure real-time information such as target/object presence, its movement, angular position, velocity, and range from the sensor.

The Demorad platform provides both hardware and software that allows for very fast evaluation and development of 24 GHz radar without the need to have RF microwave and signal chain system expertize, and significantly reduces development time and system expertize during product development phases.

A high performance RF and analog full signal chain including DSP processing, that is, an RF to bits solution is provided that allows for flexible processing on raw acquisition data, allowing radar experiments on a state-of-the art level hardware in a very short time.

Full software support of 24 GHz radar ICs using a software graphical user interface (GUI) and in DSP radar support function libraries with added capability to write raw data for post processing on PC using Matlab tools.

Demorad Details

The Demorad uses ADI’s 24 GHz, multichannel radar solution. The sensor consists of a single PCB with 2 transmitter/4 receiver antennas on the front side connected to the 24 GHz RF chipset and data  acquisition ADC’s and DSP on the reverse side. This forms the basis for a reference design that customers can use to build their final product design.

Figure 2. Demorad full signal chain.

The Demorad uses FMCW radar to detect range and velocity of objects up to 200 m away with a resolution of approximately 75 cm. The field of view (FOV) is approximately 120° in azimuth and 15° in elevation based on the antenna array design. By combining antennas as used in digital beam forming (DBF), the Demorad uses DBF to calculate angular information in the FOV.
