Sarsen Technology Limited :: Danville Signal Processing :: dspFlash™ SHARC & Blackfin Programmer Version 2.0

Danville's dspFlash™ SHARC & Blackfin Programmer 2.0 is a production programmer that supports Blackfin and third generation SHARC DSPs. Thousands of DSP/flash memory configurations are supported, all you need to use the Programmer is a standard ADI JTAG connection on your target.

The dspFlash™ programmer is connected via USB to a PC running Windows 2000, XP or Vista, with the target device connected via a removable ribbon cable to a standard ADI JTAG connector. Working in conjunction with the dspFlash™ programmer is the dspFlash Windows software program; this software is used to specify the target DSP, flash device, chip select, file format and data file.

Configurations can be saved for later use and uploaded to the dspFlash™ programmer to its internal SDRAM. All the data then resides in the dspFlash programmer so it doesn't need to be downloaded each time when programming multiple devices saving vital production time. The programmer is faster than an ADI HP-USB ICE and the VisualDSP++ flash programming utility!

The dspFlash™ Windows application is frequently updated to support new Analog Devices DSPs and flash devices.

JTAG, which stands for Joint Test Action Group, was an industry group formed in 1985 to develop a method to test populated circuit boards after manufacture. At the time, multi-layer boards and non-lead-frame ICs were becoming standard and making connections between ICs not available to probes. The majority of manufacturing and field faults in circuit boards were due to solder joints on the boards, imperfections in board connections, or the bonds and bond wires from IC pads to pin lead frames. JTAG was meant to provide a pin-out view from one IC pad to another so all these faults could be discovered. The industry standard finally became an IEEE standard in 1990 as IEEE Std. 1149.1. Another term that refers to the same process of testing is Boundary Scan - a method for testing interconnects (thin wire lines) on printed circuit boards or sub-blocks inside an integrated circuit.

SHARC is the name of a family of high performance 32-bit floating-point processors based on a Super Harvard Architecture. SHARC Processors dominate the floating-point digital signal processing market, delivering exceptional core and memory performance complemented by outstanding I/O throughput. The industry-standard SHARC family makes floating-point processing economical for applications where performance and dynamic range are key considerations, such as home audio, professional audio, automotive audio, medical, industrial, and instrumentation products. The Analog Devices SHARC Processor portfolio currently consists of three generations of products providing code-compatible solutions ranging from entry-level products priced at less than $10 to the highest performance products offering fixed- and floating-point computational power to 400 MHz/2400 MFLOPS. Irrespective of the specific product choice, all SHARC Processors provide a common set of features and functionality usable across many signal processing markets and applications.
