ADSP-BF527

Low Power Blackfin Processor with Advanced Peripherals
Manufactured by:

Product Details

The high performance 16/32-bit Blackfin embedded processor core, the flexible cache architecture, the enhanced DMA subsystem, and the dynamic power management (DPM) functionality allow system designers a flexible platform to address a wide range of portable applications, including consumer, communications and industrial/instrumentation.

With the combination of peripherals which enable glue-less connectivity to networked devices such as Ethernet or WiFi 802.11 a/b/g modules and power efficient signal processing, the ADSP-BF527 is well suited to IP connected applications such as VoIP Phone or IP Camera.

The VoIP challenge to the embedded-system designer is to choose a processing solution that is cost-effective, easy to deploy and scaleable in performance across market spaces. A “sweet spot” embedded-solution approach is to design with a platform that can implement a low channel count basic VoIP solution, yet retain sufficient capacity for value added capabilities and services – such as video, music, imaging and system control. Unlike traditional VoIP embedded solutions that utilize two processor cores to provide VoIP functionality, the ADSP-BF527 provides a convergent solution in a unified core architecture that allows voice and video signal processing concurrent with RISC MCU processing to handle network and user-interface demands. This unique ability to offer full VoIP functionality on a single convergent processor provides for a unified software development environment, faster system debugging and deployment, and lower overall system cost.

IP protection has become a necessary part of today’s embedded computing applications. The ADSP-BF527 provides a security scheme which balances flexibility and upgradeability with performance through the inclusion of a firmware-based solution including OTP (One Time Programmable) memory to enable users to implement private keys for secure access to program code.

EMULATOR-USB & HP USB ICE Circuit Diagram

Product Details

Analog Devices’ cost-effective Universal Serial Bus (USB)-based emulator and High performance (HP) Universal Serial Bus (USB)-based emulator each provide an easy, portable, non-intrusive, target-based debugging solution for Analog Devices JTAG processors and DSPs. These powerful USB-based emulators perform a wide range of emulation functions, including single-step and full speed execution with pre-defined breakpoints, and viewing and/or altering of register and memory contents. With the ability to automatically detect and support multiple I/O voltages, the USB and HP USB emulators enable users to communicate with all of the Analog Devices JTAG processors and DSPs using either a full speed USB 1.1 or high speed USB 2.0 port on the host PC. Applications and data can easily and rapidly be tested and transferred between the emulators and the separately available VisualDSP++ development and debugging environment(sold separately).

The plug-and-play architecture of USB allows the emulators to be automatically detected and configured by the host operating system. It can also be connected to and disconnected from the host without opening the PC or turning off the power to the PC. A 3-meter cable is included to connect the emulators to the host PC, thus providing abundant accessibility to hard to reach targets.

The HP USB-based emulator also supports the Background Telemetry Channel (BTC), a non-intrusive method for exchanging data between the host and target application without affecting the target system's real-time characteristics.

Most Helpful Review

After having working with Blackfin for six years; I feel I know it quiet well. Still we have lost a lot of time (and hence money) using the BF527. The documentation contains a lot of errors. An example is a name clash on register bit names. One of the bits were renamed in the header files, but not in the manual. That took a lot of time to find. The USB controller deserves a chapter on its own. It is highly defective. For instance you have eight DMA channels; but only one can be used at a time if you plan to use DMA mode 1. That is required for Tx endpoints due to another defect. For RX endpoints double buffering can't be used. The only way AFAIK is to set the MaxPacketSize to that of the endpoint. Hence, this influences your deors. It's a tough job finding a mode constellation that will work for you. Time you could have spent making a brilliant product. Until recently, the AD IDE for BF527 was VisualDSP. It's like a box of chocolate. You never know what it does. Actually recently we ran into a compiler error generating buggy code. The button bars come and go. In these days it insists to do a full recompile every time I connect to the target using JTAG. When profiling, don't reset the profiling before you have stopped collecting data. VDSP crashes. Sometimes JTAG connections are lost. Sometimes the emulator crashes. For every file it compiles it checks out a license from the server and hands it back. It slows down the compilation process. JTAG configurations vanish from time to time. I resently asked my collegues in engineering if they have ever used a development tool worse than VDSP. One of them had - but that was freeware.
